What is Continuous Testing?
Continuous testing (CT) has emerged as a crucial software development process that prioritizes testing at every stage of the Software Development Life Cycle (SDLC). The primary objective of CT is to ensure that the applications are rigorously tested throughout the development process, from code check-in to deployment, enabling quicker delivery of high-quality software.
CT provides constant feedback that allows developers to detect and rectify issues early on in the development process. This helps to reduce the time and cost associated with fixing bugs later in the SDLC. With CT, developers and testers can work closely together, enabling a culture of collaboration and accountability that ensures the software is reliable and meets the desired quality standards.
Continuous testing has also become an integral part of the DevOps process, where it is used to achieve continuous integration and delivery. It enables teams to automate the testing process using tools like Selenium, which ensures that tests are run consistently and frequently, thus enabling faster and more reliable software delivery.
A Bit About Selenium and DevOps
Selenium is an open-source tool used for automating web application testing. It allows developers and testers to write test scripts in various programming languages, such as Java, Python, C#, and Ruby, and then execute them in a web browser to verify that the application functions correctly.
On the other hand, DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to improve the software development lifecycle. It emphasizes collaboration, communication, and automation between development and operations teams to deliver software more quickly and reliably.
When these two technologies are combined, Selenium becomes a crucial component of the DevOps process. It enables continuous testing and integration, allowing teams to quickly and efficiently test their code and detect issues early on in the development process. By incorporating Selenium testing into the DevOps pipeline, developers and testers can work more closely together to ensure that their applications are thoroughly tested and of high quality before they are released to production.
Selenium and DevOps: Best Practices for Continuous Testing
1. Treat Test Code as Code
Treating test code as code means that developers should use the same processes, tools, and quality standards for test code that they use for production code. This includes using version control systems, code reviews, and automated testing tools, such as Selenium, to ensure that the test suite is reliable, maintainable, and scalable.
By treating test code as code, developers can ensure that their test suite is highly valuable and efficient. This enables faster and more reliable testing, which leads to faster delivery of high-quality software. It also reduces the risk of flaky tests and wasted time and effort in maintaining the test suite.
2. Employ a Risk-based Test Automation Strategy
Employing a risk-based test automation strategy involves incorporating a methodology into the testing procedure to identify, evaluate and mitigate the causes and consequences of terrible user experience. This enables developers to prioritize testing efforts based on the risks associated with different features or functionality.
A risk-based test automation strategy considers various factors such as time, value, effect, and history to identify the areas of the application that require the most testing. It also involves working closely with developers to leverage their gut instincts and domain knowledge, which can often provide valuable insights into potential issues that may take time to be apparent.
By employing a risk-based test automation strategy, developers can ensure that they are focusing their testing efforts on the most critical areas of the application, reducing the risk of issues that could impact the user experience or result in downtime.
3. Provide Fast Feedback
It involves generating vast amounts of data that give testers and developers new insights into explicit issues and provide managers with dashboard-level perspectives for “go, no-go” essential leadership decisions reducing the risk of delays and costs associated with fixing bugs later in the development process.
Fast feedback also facilitates collaboration between developers and testers, enabling them to work together to identify issues and make quick decisions. This approach ensures that everyone involved in the development process has access to the same information, enabling faster and more efficient problem-solving.
4. Generate and Maintain Test Data
Organizations such as banks, insurance companies, healthcare suppliers, and anyone with a mission-critical application need to test against real-world conditions. Providing QA testers and developers with high-value test data and ensuring that it evolves with the applications is essential for achieving this goal.
Test data is critical for ensuring that the software being developed is tested under real-world conditions. By generating and maintaining high-value test data, developers and testers can accurately simulate real-world scenarios, enabling them to identify potential issues that may arise in production environments.
To generate high-value test data, developers and testers need to understand the application’s requirements and real-world use cases deeply. This includes understanding the various data types and formats used in the application and ensuring that the test data is representative of real-world scenarios.
Maintaining test data is also crucial for ensuring that it remains relevant and up-to-date. This involves regularly reviewing and updating the test data to ensure that it accurately reflects changes to the application’s functionality and use cases.
5. Ensure Access to a Steady Lab and Test Environment 24/7.
A steady lab implies that all associated platforms, including supporting test environments, 3rd party tools, and APIs, are working every minute of every day with close to zero downtime.
A steady lab and test environment ensure that developers and testers have access to the resources they need to test the application continuously. It reduces the risk of delays and downtime associated with lab or environmental issues, enabling teams to focus on testing and delivering high-quality software.
To ensure a steady lab and test environment, organizations need to have a robust infrastructure in place, including backup and recovery plans in case of outages. It also involves regular maintenance and monitoring of the lab and environment to identify and address any potential issues before they become critical.
By ensuring access to a steady lab and test environment 24/7, developers and testers can work efficiently, reducing the risk of delays and ensuring that the software is rigorously tested before it is released to production.
6. Improve the Relationship between a Tester and each Developer
Keeping the teams small, encouraging inter-team collaboration, and making reports easy to access and share online can foster a culture of collaboration and accountability, enhancing the relationship between testers and developers.
Small teams facilitate better communication, allowing testers and developers to work more closely together, share knowledge, and provide feedback. This can reduce the likelihood of issues arising and enable teams to identify and address problems quickly and efficiently.
Making reports easy to access and share online is also critical for improving the relationship between testers and developers. It enables them to review test results and other necessary data in real-time, enabling faster decision-making and reducing the likelihood of misunderstandings or miscommunication.
7. Make Automation a Priority
While removing all manual testing tasks is not recommended, organizations should adopt an “automated first” mindset, focusing on areas that will be run repeatedly.
Setting up the plumbing first to let the water flow later without any worry or concern about leaks is a metaphor for prioritizing automation to enable faster and more reliable testing. By automating repetitive tasks, organizations can reduce the time and effort involved in testing, helping faster delivery of high-quality software.
Mapping out the Software Development Life Cycle (SDLC) and identifying automation opportunities are critical in prioritizing automation. This involves identifying areas of the SDLC where automation can be most effective and where manual testing can be reduced, improving overall efficiency.
In essence, making automation a priority means ensuring that the testing process is as automated as possible, enabling faster and more reliable testing, reducing the risk of errors, and improving overall software quality.
