Undoubtedly, software testing is a very large and expansive domain. However, software testing can be categorized into the following two areas: manual testing and automated testing. Both forms of testing offer different advantages and disadvantages. It’s worthwhile to know the difference between manual and automated testing as when to use one or the other to achieve the best results.
What Is Manual and Automated Testing?
Manual testing involves the execution of test cases manually by a human without any support from scripts or tools. On the other hand, automated testing involves the execution of test cases with the help of tools, scripts, and software.
Testing is essential to the success of any software project. The type of testing used for a software project should depend on a number of factors, such as project requirements, suitability, budget, expertise, and timeline. Time, quality, and cost are all vital factors for every software project. Therefore, one of the main goals of a software project should be the reduction of the cost and time needed for completion while maintaining or exceeding the quality of output. Depending on the software project, one type of testing over the other may be more suitable for the accomplishment of this goal.
Manual Testing vs. Automated Testing
Both automated testing and manual testing cover extensive areas. In each category, there are different testing methods available. Some examples of the most popular testing methods include black box testing, white box testing, performance testing, integration testing, load testing, and system testing. Some of these methods are best performed through manual testing while others are more suitable for automated testing.
- Due to human error, the rate of inaccuracies is relatively high for manual testing. As a result, manual testing is less reliable.
- Manual testing is relatively time-consuming and can take up a substantial amount of human resources.
- Investment is a requirement for human resources.
- If the test cases are only run a few times, manual testing is feasible. However, if the test cases will be run frequently, manual testing isn’t very practical.
- Manual testing is compatible with human observation. Therefore, manual testing may be ideal if the goal is an improved customer experience or user-friendliness.
- Thanks to tools and scripts, automated testing is more reliable than manual testing in most cases.
- Automated testing is faster than manual testing due to the use of software tools for the execution of test cases.
- Investment is needed for software tools.
- If the test cases are run repeatedly for an extended period, automated testing is far more feasible than manual testing.
- Automated testing may not be ideal if a good customer experience or user-friendliness is not the goal.
Importance of Using Automated Testing in DevOps Environment
In a DevOps environment, automated testing is generally the preferred option for the following scenarios and areas:
- Load testing: Automated testing is the best way to efficiently complete testing when it comes to load testing.
- Regression testing: If the code changes frequently, automated testing is ideal to run regressions in a timely manner.
- Repeated execution: If a task must be executed repeatedly for testing, automation is typically best.
Based on this information, it is up to you to decide whether manual testing or automated testing is ideal for your software project. In most cases, automated testing is ideal in terms of improving the chances of success for a software project.
