Test coverage is defined as a metric in Software Testing that measures the amount of testing performed by a set of test. It will include gathering information about which parts of a program are executed when running the test suite to determine which branches of conditional statements have been taken.
In simple terms, it is a technique to ensure that your tests are testing your code or how much of your code you exercised by running the test.
In this tutorial, you will learn
Code coverage and test coverage are measurement techniques which allow you to assess the quality of your application code.
Here, are some critical differences between booths of these coverage methods:
Parameters | Code Coverage | Test Coverage |
Definition | Code coverage term used when application code is exercised when an application is running. | Test coverage means overall test-plan. |
Goal | Code coverage metrics can help the team monitor their automated tests. | Test coverage is given details about the level to which the written coding of an application has been tested. |
Subtypes | Code coverage divided with subtypes like statement coverage, condition coverage, Branch coverage, Toogle coverage, FSM coverage. | No subtype of Test coverage method. |
To calculate test coverage, you need to follow the below-given steps:
Step 1) The total lines of code in the piece of software quality you are testing
Step 2) The number of lines of code all test cases currently execute
Now, you need to find (X divided by Y) multiplied by 100. The result of this calculation is your test coverage %.
For example:
If the number of lines of code in a system component is 500 and the number of lines executed across all existing test cases is 50, then your test coverage is:
(50 / 500) * 100 = 10%
For example, if "knife" is an Item that you want to test. Then you need to focus on checking if it cuts the vegetables or fruits accurately or not. However, there are other aspects to look for like the user should able to handle it comfortably.
For example, if you want to check the notepad application. Then checking it's essential features is a must thing. However, you need to cover other aspects as notepad application responds expectedly while using other applications, the user understands the use of the application, not crash when the user tries to do something unusual, etc.
