Automation testing is a big area of software testing and many different tools are available for automation. It is essential to choose the right tool for the job.
Automated testing framework:
An automated testing framework is a tool that helps automate the test cases and test scripts of the organization. It may be operating system or language-specific. Automation testing frameworks are used to write test scripts easily without writing code in low-level languages.
In addition, automation testing frameworks are very useful for test cases that are repetitive and time-consuming.
Below are some of the advantages of using automation tools:
How to Automate Testing
1.Faster execution time:
The test cases can be executed as and when required, so there is no need to wait for the test cases to execute especially in the case of regression testing.
2.Cost effective:
Once the test scripts are written and saved, no additional resources or human intervention is required for execution, so the cost of maintenance is low.
3.Parallel testing:
Since all the tests can be run at the same time, the total execution time is drastically reduced since it does not require any manual intervention.
4.Test case coverage:
With an automation testing framework, it is easy to cover all the branches of a program since all possible combinations can be run at one go thus increasing the test coverage and hence increasing the quality of software product produced.
5.Better Reporting:
Automation testing framework can provide better reports to the client since it is an easy-to-read format.
Test Coverage:
Test coverage is a measure of how much of the functionality of a software product is in testing. When new functionality is in, test coverage ensures that the existing functionality is not affected.
In addition, test coverage is a metric useful to determine the quality of testing performed on a software product. It gives an idea about how much of the product has been covered by executing test scripts.
Test coverage measures are useful to determine whether all the requirements have been tested; or all the possible situations have been accounted for; or that all parts of an application have been adequately tested.
Types of Coverage:
Code Coverage:
Code coverage measures how many lines of code are in execution. Perhaps when test cases are executed. Code coverage is important because it tells you how much of your application has been tested.
Statement Coverage:
Statement coverage measures how many statements in your code were executed when test cases were executed.
Branch Coverage:
Branch coverage measures how many branch statements in your code were in execution when test cases were for execution.
Decision Coverage:
Decision Coverage measures how many decisions in your code were by test cases when they were in execution.
Path Coverage:
Path coverage measures all possible logical paths through your code. When path coverage is high, there are few bugs; and when path coverage is low, there are more bugs since fewer combinations have been to prove the logic.
