Continuous Testing in DevOps is a software testing type that involves testing the software at every stage of the software development life cycle. The goal of Continuous testing is evaluating the quality of software at every step of the Continuous Delivery Process by testing early and testing often.
The Continuous Testing process in DevOps involves stakeholders like Developer, DevOps, QA and Operational system.
In this tutorial, you will learn
The old way of testing was hand off centric. The software was handed off from one team to another. A project would have definite Development and QA phases. QA teams always wanted more time to ensure quality. The goal was that the quality should prevail over project schedule.
However, business wants faster delivery of software to the end user. The newer is the software, the better it can be marketed and increase revenue potential of the company. Hence, a new way of testing was evolved.
Continuous means undisrupted testing done on a continuous basis. In a Continuous DevOps process, a software change (release candidate) is continuously moving from Development to Testing to Deployment.
The code is continuously developed, delivered, tested and deployed.
For Example, whenever a developer checks the code in the Source Code Server like Jenkins automated set of unit tests are executed in the continuous process. If the tests fail, the build is rejected, and the developer is notified. If the build passes the test, it is deployed to performance, QA servers for exhaustive functional and load tests. The tests are run in parallel. If the tests pass, the software is deployed in production.
Continuous Testing is a small cog in the Continuous Development, Integration and Deployment Cycle.
Software development is not same as it is in the past we cut development from month to weeks. The current testing stack (see figure above) is titled towards UI testing. But the goal is to have more and more automated unit tests.
Test automation vs Continuous Testing
Parameter | Test Automation | Continuous Testing |
---|---|---|
Definition | Test automation is a process where tool or software is used for automating tasks. | It is a software testing methodology which focuses on achieving continuous quality & improvement. |
Purpose | A set of similar or repetitive tasks, a machine can execute, faster, with a fewer mistake. | The continuous testing process helps to find the risk, address them and improve the quality of the product. |
Prerequisite | Automation in testing possible without integrating continuous testing. | Continuous testing can not be implemented without test automation. |
Time | Software release can take a month to years. | Software release may be released weekly to hourly. |
Feedback | Regular feedback after testing each release. | Feedback at each stage needs to be instant. |
History | Automated testing has been done for decades to make the testing process faster. | Continuous testing is a relatively newer concept. |
