How To Move From Manual to Automation Testing

Aggregated on: 2022-04-21 20:35:38

With software requirements changing at lightning speed in an agile environment, more and more organizations look to inculcate more atomic development cycles for accelerating their Time To Market (TTM). A 2021 study by digital.ai has discovered that 86% of software development teams have adopted agile, up from 37%, a year ago. This shift to more agile software development methods has led to a simultaneous demand for more efficient means of software testing during the software is developed. Companies run the risk of suboptimal software delivery due to costly manual test case maintenance cycles as well as the lack of visibility these legacy processes bring to the table. A Statista study highlights that 32% of all Software projects fail due to the simple lack of time to test the product thoroughly.

Best Practices To Optimize Continuous Testing in DevOps

Aggregated on: 2022-04-21 18:50:38

As more and more organizations undergo digital transformations, we see a growing trend towards cloud storage, cloud computing, and strategizing testing on the cloud with a DevOps mindset. Continuous testing is an integral part of DevOps. The QA teams who use the best DevOps test strategy see the importance of faster software development and delivery as a competitive business differentiator. The development team aims to incorporate continuous testing into the development process so that the users can receive a high-quality product with great features without jeopardizing the software product’s reliability. The team can uncover flaws and errors far in advance by testing continually throughout the software development and delivery process, making it simple to address minor issues before they become large, unmanageable losses. For strategic continuous testing, a well-designed DevOps test automation strategy is essential. Continuous testing reduces the time it takes to complete tests. It saves the developer’s time while uncovering errors and is an important collaborative method that emphasizes good communication and coordination between teams to achieve the best results. The gap between development and testing can be bridged by providing timely feedback to developers.

Aggregated on: 2022-04-21 17:05:38

Previous Articles on CDC: SaaS Galore: Integrating CockroachDB with Confluent Kafka, FiveTran, and Snowflake CockroachDB CDC Using Minio as Cloud Storage Sink - Part 3 CockroachDB CDC Using Hadoop Ozone S3 Gateway as Cloud Storage Sink Motivation I was working on a demo requiring data to be serialized in Avro format. CockroachDB supports Avro for change data capture when used in conjunction with Confluent Schema Registry. We have documentation on CDC with Avro using a local Schema Registry, but what is missing is hosted Schema Registry on Confluent Cloud. We are going to address that in the short term but in the meantime, this tutorial should suffice. As of the time of this article, the hosted setup has nuances and I attempt to document it in the meantime.

How to Improve Your Wordpress' Website Security

Aggregated on: 2022-04-21 03:35:38

WordPress security has been an important topic ever since the content management system was released back in 2003. As with any highly popular piece of software with a long and rich history, the CMS can sometimes become the target of WordPress hackers. Hostile actions could include a cross-site scripting attack, sql injections, brute force attacks, and a number of other ways to gain unauthorized access. As hackers gain experience in finding new ways to exploit WordPress vulnerabilities, developers and security specialists get better at creating sites that are more difficult to breach. There are things developers and WordPress site owners can do if they don’t want hackers to gain access and bypass server security. In this article, we will discuss some actions a WordPress admin can perform to prevent a platform from becoming one of many hacked websites.

Three Ways to Import Data With Postgres

Aggregated on: 2022-04-21 03:35:38

What is a database without data? Postgres provides multiple options to import data from files. You can use the COPY command, restore from a backup, or load in a CSV with a SQL GUI tool. The fastest and easiest method will depend on your setup and how the data exists right now. Method 1: Using the COPY Command for Postgres The COPY command can import data to Postgres if access to text, CSV, or binary format data. For example, the COPY TO command outputs the content of a table to a file. You can also use the COPY FROM command to load the data from a file to the table. The file mentioned in the COPY command must be accessible by the Postgres user and should be specified from the perspective of the Postgres server.

Building an AutoML Application

Aggregated on: 2022-04-20 22:50:38

Machine learning (ML) has been developed and growing fast. It also depends on an expert in ML to develop the ML model, i.e. pre-processing, building model, feature engineering, tuning of hyper-parameters, etc. Data scientists have many demanding responsibilities, and challenges. These challenges include the selection of the best algorithm, modification of this algorithm over many iterations, and identification and tuning of the hyper-parameters many times. Despite going through difficult processes, it is worth noting to watch the ML model beat expected accuracy. There is the myth that the developers love to overdo the coding. Many steps that are performed by data scientists are repeatable and time-consuming which makes these steps ideal candidates for automation [1]. Figure 1

How to Write an Effective Penetration Test Report

Aggregated on: 2022-04-19 23:05:37

What Is an Effective Penetration Testing Report? Following the recent trend of cyberattacks against IT infrastructure, service organizations have a steady rise in demand to conduct penetration testing on IT resources to ensure all vulnerabilities are identified and mitigated. Penetration testing is a technical cybersecurity procedure targeted at finding security flaws in a company’s internal and external networks, web applications, and systems. After a penetration test is completed, the testers must provide a penetration test report that documents the security issues identified during the assessment. A penetration testing report is issued to an organization to present the risk associated with the security vulnerabilities identified in the infrastructure and provide remediation steps to fix the identified risk exposure. The test objective can be fulfilled based on the adequacy of the penetration testing report. Hence, a well-documented penetration testing report is as important as the penetration test itself. Below you can see the difference between the two types of penetration testing reports:

An Introduction to PCI Compliance

Book Review: Python Distilled

Aggregated on: 2022-04-19 19:50:37

Python Distilled by David M. Beazley is a pragmatic book that presents some of the most important topics about the Python programming language in a concise form, designed to make it easier to find out the most relevant information bits in a context where resources abound and frequently are just too overwhelming. Book Structure and Contents The book is organized into 10 chapters. It starts off with the basics, such as variables, data types, operators, expressions, control flow, and looping. Compared to other books I have read recently, it uses a smaller font size, which is quite readable to me, but it may be less comfortable for some readers. On the other hand, it contributes to making it a lighter and less thick book, compared with other programming manuals. The book uses no syntax highlighting, but code samples are short enough that actually this does not become a problem at all.

Java Bytecode Simplified: Journey to the Wonderland (Part 1)

Aggregated on: 2022-04-18 11:50:36

There are two ways to see a thing. One, see it as it appears to us; two, see it and appreciate it. For example, we get light when we switch on a lightbulb. We press the button and then get busy with our life. Pretty simple, but boring. On the other hand, if we know how the light gets energy from an electrical power grid far from our home with wires, and while traveling through the wires and filament, the filament heats up and starts emitting photons, we get to see in the light; we can then appreciate the blessing. In the same way, when we write a piece of code, and if we know the mechanism behind it, we can then appreciate it more, how excellent engineering effort went into it, making our life so amazing.

HTAP: One Size Fits All?

Aggregated on: 2022-04-18 09:05:36

An important idea in the database world is that specialized databases will outperform general-purpose databases. Michael Stonebraker, an A. M. Turing Award Laureate and one of the most influential people in the database world, also discussed this in his paper, One Size Fits All: An Idea Whose Time Has Come and Gone. This is a rational judgment because it's tough enough to build a database that supports either Online Transactional Processing (OLTP) or Online Analytical Processing (OLAP) workloads, let alone one that supports both at the same time. But the dilemma is, that today, many users are facing increasing demands with mixed OLTP and OLAP workloads. How do we crack this then?

How to Best Fit Filtering into Vector Similarity Search

Aggregated on: 2022-04-18 03:20:36

Attribute filtering, or simply "filtering," is a basic function desired by users of vector databases. However, such a simple function faces great complexity. Suppose Steve saw a photograph of a fashion blogger on a social media platform. He would like to search for a similar jean jacket on an online shopping platform that supports image similarity search. After uploading the image to the platform, Steve was shown a plethora of results of similar jean jackets. However, he only wears Levi’s. Then the results of image similarity search need to be filtered by brand. But the problem is when to apply the filter? Should it be applied before or after approximate nearest neighbor search (ANNS)?

Leverage Docker to Produce Classic Deployment Artifacts

Aggregated on: 2022-04-17 20:50:42

Traditionally, deployment artifacts were types of archives that were transferred to the target environment and installed there. They could be simple .zip archives with binaries, Java's .jar or .war files, or simply .exe executables, among others. It is worth saying that this approach implied preliminary preparation, like installing and configuring all software dependencies. The situation changed when Docker appeared. Moreover, the principle changed: now we operate Docker images like some self-sufficient sealed units containing everything the app needs to work. But we have to admit that both principle and technology are relatively new to the industry. Many companies still rely on a VM-based approach and classic deployment artifacts. And it's quite clear why they do this: infrastructure is already bought; Ops teams are trained on how to deploy, manage and monitor applications; and so forth. In two words, this journey seems to be very long and tough. To mitigate this, we can use the well-known step-by-step method with gradual adjustments to the existing delivery pipeline.
