Best Practices & Tools for DevOps Testing

DevOps Testing

What is DevOps?

DevOps Lifecycle

  • Plans: The DevOps team identifies business needs and gathers feedback from users during the planning phase. To maximize the value to the business and provide the desired result, developers also create a roadmap of the project at this stage.
  • Code: In this stage, the application code is created and the process is streamlined by using tools and plugins like Git or GitHub to minimize lousy coding practices and shortcomings in application security.
  • Build: In the build stage, developers commit the code to the shared repository with tools like Gradle or Maven.
  • Test: In the test phase, the build is deployed to the test environment so that the application quality can be ensured by running different tests such as security, user acceptance, integration, performance, and more using tools like Selenium, JUnit, etc.
  • Release: When the build is ready to be deployed in the production environment after passing tests, releases are scheduled by the operations team.
  • Deploy: In the deployment stage, Infrastructure-as-Code uses different tools to build and deploy the production environment.
  • Operate: Once the release is accessible to the end-users, the operations team works on server configuring and provisioning using tools like Ansible, Saltstack, CFEngine, or Chef.
  • Monitor: As the name suggests, in the monitoring stage, the DevOps pipeline is monitored according to the collected information on application performance, user behavior, and so forth. With environment monitoring, teams can easily identify bottlenecks that affect productivity.

From Agile to DevOps

Best Practices For DevOps Testing

1. DevOps Test Culture

  • Encouragement of collaboration around testing and test results analysis instead of confrontations between testers and developers for code repairs.
  • Test coverage and creation terms have been consented to by the DevOps team.
  • Leaders should consider testing as a strategic part of the project development instead of seeing it as a cost that can be reduced. They need to budget money and time to provide test training resources, frameworks, tools, management and creating assessment policies for developers they want in the DevOps team.
  • Dev teams should embrace the test creation and result analysis, while the Ops teams should plan and execute cross-functional tests.

2. Continuous Test Strategies

3. End-to-End Test Integration

  • Conducting tests on the changes in the application before integration using a private instance to ensure the code changes do not break the branch. Some of the testing methods to do so are static code analysis, unit testing, performance testing, regression, scanning and functional testing.
  • In the pre-integration testing stage, automated tests should be created for use in later testing stages in the pipeline.
  • To verify test results from the pre-integration test, the DevOps team should conduct assessments on the code at the time of committing code.
  • In the build stage, tests should be performed to identify whether the integrated build meets the acceptance criteria.
  • To make sure that the performance and functionality of the build images meet the assessment criteria, performance and functional tests must be committed during the code testing process.
  • Similarly, at other stages such as regression, system tests, and delivery, a set of tests needs to be conducted to ensure that the code and application meet the expected assessment criteria.
