True Component-Testing of the GUI With Karate Mock Server

Aggregated on: 2022-05-31 21:51:03

In my previous post, I discussed the difference between tests that target code versus those that target an API. A subset of the second category are automated tests for a web/mobile interface that mimic user behavior and validate the rendered responses, using Cucumber/Selenium, Cypress, or any other stack. These are typically written and executed as end-to-end tests, in that they require a production-like setup of the backend; but that needn’t be the case. GUI tests can turn into true component tests if they target the browser, but with a fully mocked backend. In a complex microservices architecture, it makes good sense to do so. In this article, I will highlight the motivation for writing those tests, and in a follow-up, I will give tips and examples on how to do so with the Karate framework. Feel free to dig into its excellent document if you can’t wait. Separation of Concerns Between Frontend and Backend Traditionally, in the world of JSP and JSF, the backend of web applications would contain mostly display and rendering logic, on top of handling all business rules. With so much server-side rendering, you had no choice but to spin up the actual backend code if you wanted to automate a user scenario in the browser. Without the backend, nothing much would work.

When Disaster Strikes: Production Troubleshooting

Aggregated on: 2022-05-31 21:51:03

Tom Granot and I have had the privilege of Vlad Mihalcea’s online company for a while now. As a result, we decided to do a workshop together talking about a lot of the things we learned in the process. This workshop would be pretty informal ad-hoc, just a bunch of guys chatting and showing off what we can do with tooling. In celebration of that, I thought I’d write about some of the tricks we discussed amongst ourselves in the past to give you a sense of what to expect when joining us for the workshop but also a useful tool in its own right.

Reasons Why DevOps Adoption Might Be of Help for Business

Aggregated on: 2022-05-31 20:51:03

As far as this modern and tech-oriented IT domain goes, DevOps has become a standard to judge operations’ overall efficiency and smoothness. However, like it is with everything in the world, there is still a sizeable chunk of enterprises in the process of either understanding what it means or completely not being aware of it at all. In this post, we will try to cover a few crucial points that will include a brief overview of DevOps and why DevOps adoption might be helpful for businesses.

Functional vs. Non-functional Testing: Can You Have One Without the Other?

Aggregated on: 2022-05-31 20:21:03

Functional and non-functional tests are the most popular approach to categorizing the different types of software testing. These two categories refer to the very essence of the testing process and what exactly is being tested. There are two things to know about functional and non-functional testing if you’ve never dug deep into these two testing categories before. One, the division between non-functional and functional testing is not set in stone, and for some testing types, categorizing them is no easy feat. Two, both functional and non-functional testing are essential for the success of your software testing project, albeit in different ways. Today, we will take a closer look at the difference between functional and non-functional requirements, where these two types of testing stand in the software testing process, and how they influence the cost of testing.

How to Perform Visual Regression Testing Using Playwright

Aggregated on: 2022-05-31 17:36:03

Regression testing verifies that system changes do not interfere with existing features or code structure. They are part of almost every test suite in software development lifecycles. It is common for developers to change or add a code section and unintentionally disrupt something that is working just fine. Visual regression testing functions on the same logic but confines it to the visual aspects of the software. It works by comparing two images and automating complicated scenarios, like when we cannot identify the elements in the DOM tree. However, visual regression can be used on any website.

Creating an Event-Driven Architecture in a Microservices Setting

Web Performance Testing — What, Why, How of Core Web Vitals

Aggregated on: 2022-05-31 16:21:08

A website needs to be constantly tested and optimized to be in line with Google's web and SEO guidelines. As a result, it has an advantage over others in terms of visibility, brand image, and driving traffic. However, to tactically assess the website's performance, it needs to be measured in a well-thought-out manner. Core Web Vitals is a key performance metric that analyzes the website's performance by investigating the data and provides a strategic platform to scale up the website's user experience. This article will learn about web performance testing and how Core Web Vitals plays a crucial and strategic part in it. What Is Web Performance Testing? Web performance testing is executed, so that accurate information is provided on the application's readiness by monitoring the server-side application and testing the website. This is done by simulating a load that is in line with real conditions so that the expected load can be supported by the application that has been evaluated.

Setting Up a Dedicated Database Server on Raspberry Pi

Aggregated on: 2022-05-31 14:36:03

There is certain gratification when you get a little “naked” mini-computer board to run the software you install on it. Maybe even your own application. Most (if not all) of the real-world applications I have implemented connect in one way or another to a database. It’s not a secret that relational databases are the most popular option in mission-critical applications that require truly ACID compliance. So, installing a good performant SQL database in a Raspberry Pi is, to say the least, a fun exercise to do. Even though the Raspberry Pi can connect to the Internet and consume a Database as a Service (DBaaS) like SkySQL, smaller applications might benefit from having a local-only database running on the same device. In this article, I show you how to install and set up a MariaDB server on a Raspberry Pi 4 Model B with 8 GB of RAM that you can connect to your local network through WiFi or Ethernet. You can use models with much less RAM memory as well.

How to Pass Arguments to Events Like On:Click in Svelte

Aggregated on: 2022-05-31 00:51:03

Svelte events are the way we add interactivity to components in Svelte. A common issue with Svelte events is adding arguments to functions called within them. For example, suppose we have a basic counter, which increases any time the user clicks on it: HTML {x}" data-lang="text/html"> <script> // we write export let to say that this is a property // that means we can change it later! let x = 0; const addToCounter = function() { ++x; } </script> <button id="counter" on:click={addToCounter}>{x}</button> This works fine, but let's say we want to change it so that we increase the counter by a certain amount whenever it is clicked. We might try changing the code to something like this:

What Is the Future of Manual Testing?

Aggregated on: 2022-05-30 21:51:03

Manual testing is considered the preliminary testing phase which generally evaluates the behavior of the app developed, by performing the step-by-step assessment of the requirement specification analysis record. The prime objective of manual testing is to ensure that the app works extraordinarily and fine without any sort of bugs and functional defects and also as per the requirement specification documents. Well, the future of manual testing tends to bit closer and closer to Software Development in functioning and requirements. The modification and operational developments in manual testing prove that it is necessary for manual testers for improving their skills and daily working styles.

Where Does Middleware Stand in Web Development?

Aggregated on: 2022-05-30 16:36:02

Before we go ahead with the topic, the readers must have some prior knowledge about web development and Middleware. As observed by its name, Web development is a field of computer science. The developers are responsible for developing websites, whether they are for the internet, intranet, single-page website, blog sites, or complete social media platforms. Middleware acts as a glow-in as it provides the path between the front end and back end of a computer or android based application. The main focus of Middleware is to provide those services which are out of reach from the operating system. This can be demonstrated from a simple example that Middleware is such an architect that is not available on windows or an android based devices. Still, the developer needs that specific part to complete their development, so Middleware comes into play and provides something to them. It acts as an unsung hero in web development. The Relationship Between Middleware and Web Development In web development, Middleware lies between the applications and the operating system. As to the previous discussion, it becomes very obvious that the role of Middleware is very important in web development. While it only acts as a hidden layer, which means the user and even the developer can't see it, if we remove this hidden layer, the user will not be able to run the application. The developer will be unable to develop something like that. Middleware provides communication between the inputs and outputs while the developer can work on developing the website. For a better understanding, below is a figure which can help to improve the concept.

How to Streamline the Customer Experience with Monads in Kotlin

Aggregated on: 2022-05-29 23:51:02

At my company, we see a lot of SDKs and Swagger-generated clients that could throw exceptions at any time. This could be a fault in our logic, or it could be a fault with some 3rd party SDKs that have no rhyme or reason to how their exception handling works. But either way, when our customers want to fetch a Git commit history for a service, they do not want to be greeted with an error message. We've seen GitHub go down during a customer demo and 3rd party integrations throwing other unexpected exceptions. Overall, it was a very discouraging experience for our customers that we had no control over.

Develop a Daily Reporting System for Chaos Mesh To Improve System Resilience

Aggregated on: 2022-05-29 20:51:02

Chaos Mesh is a cloud-native chaos engineering platform that orchestrates chaos experiments on Kubernetes environments. It allows you to test the resilience of your system by simulating problems such as network faults, file system faults, and Pod faults. After each chaos experiment, you can review the testing results by checking the logs. But this approach is neither direct nor efficient. Therefore, I decided to develop a daily reporting system that would automatically analyze logs and generate reports. This way, it’s easy to examine the logs and identify the issues.

Reference: Non-Printable Characters List

Aggregated on: 2022-05-28 16:06:01

Non-printable characters on Linux, macOS, or Windows are characters that do not represent a symbol, character, or number that is part of the document's text, but rather are used for things like character encoding. A full list of all non-printable characters along with their decimal and hexidecimal codes are shown below. How to Find Non-Printable Characters in a File If you need to see all nonprintable characters in a document, you can use cat -v filename.txt in terminal to find them, where filename.txt is the file you want to show. The contents of the file, along with the non-printable characters in caret notation will be shown in your terminal window.

Introduction to Serverless With AWS Lambda and Bitrise API: Part 1

Aggregated on: 2022-05-28 16:06:01

In the early days of software development, anyone seeking to develop a web, mobile, or backend application had to own the hardware required to run a server, which is an expensive process. Then, when cloud computing came, it became possible to lease server space or a number of servers remotely. The developers and companies who rent these fixed units of server space generally overbuy to ensure that a spike in traffic or activity won't exceed their monthly limits and break their applications. Because of this, a lot of the server space that gets paid for can be wasted.

Site Reliability Engineers (SREs) have a considerable set of tasks to juggle no matter where they work or how long their company has had an SRE practice. But if you’re the very first SRE to join an organization – as many SREs are these days, given that the SRE trend is trickling down into smaller and smaller companies – you face a special group of challenges. You may find it difficult to get buy-in for SRE from other technical teams. You may struggle to know how to convince your boss that the company’s decision to hire an SRE is paying off. You probably worry that you’ll end up being over-extended because you are on the only SRE at the place, and so on.

Better Scaffolding with jQuery - Part I

Aggregated on: 2022-05-27 01:21:00

Grails scaffolding works great out of the box. Today I want to see how we can improve adding data to the many side of a one-to-many relationship using jQuery, jQueryUI's Dialog, and some Ajax. Using the same domain objects as my previous article I want to show how we can add Reminders to an Event without needing to navigate to a new page, assuming it is ok to create events without reminders. For the sake of clarity, here are the domain objects. class Event { String name static hasMany = [reminders: Reminder] static constraints = { } } class Reminder { ReminderType reminderType Integer duration static belongsTo = [event:Event] static constraints = { } String toString() { "${reminderType} : ${duration}" } } Note that in Reminder I've added a ReminderType. This is a simple Enum with the values Email and SMS. I did this to add a bit of meat to the Reminder form. Once you have a new grails application up and running you'll need to download a couple of things. The first is jQuery. The easiest way to get this in grails is to simply install the plugin. Execute "grails install-plugin jquery" and then in the views/layout/main.gsp modify the g:javascript tag to use "jquery" instead of "application" for the library attribute.

Apache Harmony Finally Defeated

Aggregated on: 2022-05-27 00:51:00

Some have probably been expecting it for a long time, and this week it finally happened. Apache Harmony, an open source cleanroom implementation of Java was moved to the Apache Attic, where inactive projects are sent. The project management committee voted 20 to 2 in favor of discontinuing the project. One of the votes against moving Harmony to the Attic was PMC chair Tim Ellison, who thought it was too early to deactivate Harmony. But Harmony was probably already dead and buried once it's primary corporate sponsor, IBM, switched its support to OpenJDK last year. Android has not gotten invovled in the Harmony project recently because of their ongoing lawsuit with Oracle.

Last week, demonstrated building and Android application that queried Hudson remote api through REST calls, which returned back JSON objects; in Android App to Monitor Hudson Rest API. The application was very basic, in that all that could be done was launch it and there were no configurations, or customization to make the application more user friendly. This week the application will be enhanced to use menus and add additional screens or activities to allow a user to configure the application to point to a Hudson remote server of their choosing. The application will also save the configuration state so the user doesn't have to re-enter the information after the application has shutdown. The first step in customizing the application will be to get rid of the default android icon, and place a customised icon. Android supports .jpg, .gif, .png, and .bmp image formats. To customize the default icon, simply open the res/drawable folder and put the image in this folder. The image should be a 48x48 size .PNG image.

How to Add a Blank Directory to Your Git Repository

Aggregated on: 2022-05-26 21:51:00

Sometimes in Git, we want to preserve a directory for use within a repository, but keep it empty of files. There are many reasons why you'd want to do this, but perhaps either the folder is used to store files the person cloning the repository needs to create, or a script creates custom files to put into that folder. If we want to create a blank directory, we can do that easily, but it won't be pushed when we use git push to push it to our remote. As such we need to do something slightly different.

Software developers enjoy having free access to resources when developing software programs. It is, however, a high level of concern having to deliver the right amount of security and privacy during that process. Nevertheless, it is of high importance to note that software development is usually prone to security issues due to the peculiarity of developers using their preferred devices. Through the process of using their preferred devices, your local network gets connected to another unrecognized computer that probably has different software applications installed and even a different anti-virus policy.

Cloud-Native Core Banking Modernization With Apache Kafka

Aggregated on: 2022-05-26 17:06:00

Most financial service institutions operate their core banking platform on legacy mainframe technologies. The monolithic, proprietary, inflexible architecture creates many challenges for innovation and cost-efficiency. This blog post explores an open, elastic, and scalable solution powered by Apache Kafka that can look to solve these problems. Three cloud-native real-world banking solutions show how transactional and analytical workloads can be built at any scale in real-time for traditional business processes like payments or regulatory reporting and innovative new applications like crypto trading. What Is Core Banking? Core banking is a banking service provided by networked bank branches.

What Is a CSRF Token?

Aggregated on: 2022-05-26 15:06:00

Cross-site request forgery (aka cross-site reference forgery) is a form of web application attack. The hacker tricks users through malicious requests into running tasks they do not intend to execute. Therefore, the webserver needs a mechanism to determine whether a legitimate user generated a request via the user’s browser to avoid such attacks. A CSRF token helps with this by generating a unique, unpredictable, and secret value by the server-side to be included in the client’s HTTP request. When the subsequent request is made, the web server validates the request parameter that contains the token and rejects those that don’t. The approach is commonly used to prevent CSRF attacks since it is almost impossible for the hacker to construct a complete, valid HTTP request to ambush a victim. We discussed earlier how cross-site scripting vulnerabilities are among the most common forms of attacks involving the execution of malicious code on a victim’s browser. Though a CSRF may sound similar to XSS attacks, there are fundamental differences in how they are carried out.
