Continuous Testing in DevOps : Definition, Steps and Tools

CONTINUOUS TESTING

What is Continuous Testing? 

It is a methodology for software testing wherein the product is tested frequently and during the Continuous Delivery (CD) process. It requires automated tests to make sure that teams receive instant feedback, allowing them to eliminate as many uncertainties during the software development. In addition, team members will constantly learn about their products and what can be done to improve consistency and reliability.

Further, it enables automated feedback on the business risks associated with a release candidate. It assists development teams in meeting business objectives and managers in making informed decisions on maximizing the value of a release. 

On the other hand, it isn't just about adding more test automation to the process. DevOps Online Training provides agile development teams with ongoing integration and continuous delivery. This allows them to launch products on the market more efficiently.

Continuous Testing in DevOps includes developers, quality assurance, and operational systems. DevOps Course Online allows you to explore your expertise in DevOps, methodologies, and instruments.

How Is Continuous Testing and Test Automation Different?

Steps To Perform Continuous Testing:

1. Develop Stable Automation –

The first step toward Continuous Testing is to develop reliable automation. Once all testing problems have been resolved, you will have stable automation. Smart reporting makes a substantial distinction between actual problems and false negatives.

Assess the team's experience level to decide if code-level scripting tools like Selenium, Appium, or even Espresso/XCUITest are relevant. Otherwise, you can choose a codeless solution. If you select an incompatible platform with your team's skillset, you will have difficulty maintaining stable automation.

2. Maintain a Daily Schedule –

Your next step is to integrate a limited number of scripts into a routine pattern that runs at least daily automatically and successfully through multiple platforms.

When you run with a limited number of false negatives, you show your company that your automation process is efficient. This reliance is a vital step in that process of continuous Testing.

3. Accelerate Coverage–

Once the automated processes are stable and reliable, the next step is to increase test coverage.

Numbers are approximate. The ultimate aim is to achieve proper test automation coverage for functional and non-functional tests. Actual coverage can be as high as 95% or even 90%. However, consider that something that is not automated can occur at the end, slowing down the processing speed.

Here, the focus should be on a low-maintenance but up-to-date facility. Scaling up should be possible with your lab's assistance. To separate the noise from the actual failures, you'll need dozens of parallel exactions and smart reporting.

4. Maintain 95% Coverage –

The next step is to aim for coverage of 95%. To achieve this, you need extra layers of active monitoring and capacities, such as the: Virtualization of networks, Virtualization of services, Sensor mocking.

To run consistently from your CI, you'll require high-value, high-trust Testing. This enables you to achieve the continuous maturity objective.

5. Perform Continuous Testing Regularly –

The process switches from automated testing "every night" to "many times a day" (CI/CD) at this stage. This result in even faster feedback, increased accuracy, and reduced risk.

This stage is mandated for continuous delivery. This increases the system cycle flexibility and usually reduces defect resolution time by 50%.

Tools Used In Continuous Testing:

1. Katalon Studio – 

Katalon Studio is a complete continuous test tool that works with high-demand CI/CD and DevOps test automation.

Katalon Studio provides an extensive range of in-depth analyses, real-time reporting, and instant feedback. You have complete control over both the quality of your products and the performance of your team.

2. Selenium –

Selenium is a free and open-source software testing platform. It is compatible with all major browsers, including Firefox, Chrome, Internet Explorer, and Safari. Selenium WebDriver can be used to simplify the testing of web applications.

3. QuerySurge –

QuerySurge is the first-of-its-kind complete DevOps tool for continuous data testing. Among the key features are a robust API with over 60 calls, comprehensive data intelligence and analytics, easy integration into the DevOps system for continuous Testing, and the ability to quickly verify huge amounts of data.

4. Jenkins –

Jenkins is a Java-based Continuous Integration platform. This tool can be programmed through a graphical user interface (GUI) or via console commands.

5. Travis –

Travis is a GitHub-hosted Continuous testing in the DevOps platform. It is available in hosted and on-premises environments. It supports several different languages and comes with extensive documentation.

Advantages of Continuous Testing:

• Accelerate the rate of release: delivery and release more efficiently
• Transparency in communication: Remove silos between teams of development, testing, and operations
• Accelerate the testing process: Conduct parallel performance assessments to accelerate the testing process.
• Finding errors: Make sure that before releasing to production, several errors are found
• Eliminate business risks: Analyze potential issues before they develop into actual problems.

Conclusion:

Continuous Testing is a method in software engineering that involves testing early, frequently testing, testing anywhere, and automating the testing process. Continuous Testing provides actionable feedback at any step of the delivery process.
