What does test coverage mean?

Test coverage is defined as a metric in Software Testing that measures the amount of testing performed by a set of test. 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.

How do you calculate test coverage?

This metric is calculated according to the following formula: Test coverage = (number of claims covered by test cases/total number of claims)x100\%. To test this test coverage, we should divide all requirements into separate items and then link each item with the test cases that test it.

What are test coverage criteria?

Introduction. Test coverage level is the degree to which specified coverage items have been exercised by a test suite [1]. For effective testing, the notion of test coverage criteria is important because it provides a means of measuring the extent to which a set of test cases exercises a program [2].

What is difference between code coverage and test coverage?

Code coverage is measured by the percentage of code that is covered during testing, whereas test coverage is measured by the features that are covered via tests.

What is a test coverage matrix?

A coverage matrix is used to make sure that a piece of software has been thoroughly tested. It includes new feature testing, application coverage and code coverage. A coverage matrix is used to trace the requirements from the client to the tests that are needed to verify whether the requirements are fulfilled.

What is test coverage in Java?

Last update: 2014-05-24. Code coverage means measuring how much of your code is executed during your unit tests. Basically, that means that after running your unit tests, you get a report showing you how many percent of the code that was executed during the tests, and also what lines precisely that were executed.

What is difference between code coverage and functional coverage?

So, the verif engr, has to write funcitonal coverage code for A, B and C. And 100\% functional coverage means, there are tests for all the features, which the verif engr. has thought of. You have to write coverage code and then switch ON the coverage during simulation.

What is test coverage Python?

Coverage.py is a tool for measuring code coverage of Python programs. It monitors your program, noting which parts of the code have been executed, then analyzes the source to identify code that could have been executed but was not. Coverage measurement is typically used to gauge the effectiveness of tests.

What is test coverage in software testing?

Test Coverage in Software Testing. In software testing, test coverage measures the amount of testing performed by a set of test. It will include gathering information about which parts of a program are actually executed when running the test suite in order to determine which branches of conditional statements have been taken.

What is statement coverage in testing?

Statement coverage is a white box test design technique which involves execution of all the executable statements in the source code at least once. It is used to calculate and measure the number of statements in the source code which can be executed given the requirements.

What is decision coverage in testing?

Decision coverage or Branch coverage is a testing method, which aims to ensure that each one of the possible branch from each decision point is executed at least once and thereby ensuring that all reachable code is executed. That is, every decision is taken each way, true and false.

As the name suggests Test Coverage Matrix is a table (matrix) that can be used to track the testing coverage for a feature or a module. Advantages of TCM are that one can clearly visualize what all cases have been considered; and it also helps in identifying gaps in testing.
