Code Coverage Vs Test Coverage

Code coverage and test coverage are two conventional methods used to measure the efficiency of a code. Both of them follow principles that are almost the same, but should not be used interchangeably. The type of coverage we need to use solely depends on the requirements of the project.

Understanding code coverage and test coverage –

  • Code Coverage: This type of coverage is mainly based on unit testing. It essentially focuses on performing all the statements in a particular code. It provides test cases through manual testing, automation testing, and other frameworks.

Code coverage includes the percentage of testing and, Test coverage indicates the number of features performed during a testing process.

Let us now discuss Code Coverage and Test Coverage in detail.

Code Coverage

Code coverage follows the unit testing technique. Developers create unit testing and give the best output. Code coverage always tries to add recent features. The basics of Code Coverage are solely based on Unit Testing.

Steps to perform in Code Coverage

Different levels to perform Code Coverage are discussed below –

  • Branch Coverage: This type of coverage is very similar to the decision coverage technique. It involves decision-making techniques and helps to resolve issues created for decision-making statements.

Advantages of code coverage

  • Provides efficiency to the test code and a way to perform it in a better way.

Disadvantages of code coverage

  • Most of the tools are based on Unit Testing only.

Test Coverage

Test coverage involves usability testing and software testing.

Test Coverage Mechanisms –

  • Unit Testing: Unit Testing gets performed at module levels. Bugs that arise in the case of Unit Testing are different from the bugs of Integration Testing.

Steps to perform Test Coverage –

The Test Coverage tool follows some particular steps that can be mentioned below –

  • Features Coverage: Features Coverage provides maximum coverage for all the test cases. This kind of feature covers all the mandatory and optional features.

Advantages –

  • Test Coverage provides a better way to compare the outcomes for particular documents like UI/UX testing.

Disadvantage –

  • Since it follows the black box type, there is no way to do the Automation testing.

We just discussed some basic ideas about Test Coverage and Code Coverage. Now we will compare these two to get a clear view.

A Comparison between Code Coverage and Test Coverage –

The above discussion gives some basic ideas about Code Coverage and Test Coverage.

The Code coverage is white box testing and, Test coverage is Black box testing and has its benefits and disadvantages. So, we can conclude that both types of coverage depend on the nature of the project, and they are not the same.
