How can code coverage be improved?

There are a number of approaches:

  1. Write More Tests.
  2. Generate Tests Automatically.
  3. Remove Dead/Zombie Code.
  4. Remove Redundant/Cloned Code.
  5. Write/Execute More Sophisticated Tests.

How can test case coverage be improved?

Steps to improve better test coverage The first and most basic approach of test coverage is by feature. Compile a list of the most important, or most actively used features in your application, then determine if they should be included in your list of requirements and covered by tests.

How do you get 100 percent code coverage?

2 comments

  1. One of the steps into achieving the 100% coverage rule is to start with a better design. E.g. many times setter and getters are considered trivial to test and thereby causing people to skip testing them and thus lowering the coverage.
  2. Agreed, the best way to improve coverage is to write less code.

Is it possible to achieve 100 test coverage?

We can not perform 100% testing on any application. but the criteria to ensure test completion on a project is 1. all the test cases are executed with the certain percentage of pass.

How do you ensure code coverage in testing?

To calculate the code coverage percentage, simply use the following formula: Code Coverage Percentage = (Number of lines of code executed by a testing algorithm/Total number of lines of code in a system component) * 100.

How can I improve my JaCoCo?

For the code coverage to increase , one would need to run the tests with the coverage enabled and then view the report generated locally to see the areas covered by jacoco during its coverage parse, then from these one would see the methods (per class) that needs to be covered from the view of the jacoco agent.

How much code coverage is enough?

With that being said it is generally accepted that 80% coverage is a good goal to aim for. Trying to reach a higher coverage might turn out to be costly, while not necessary producing enough benefit. The first time you run your coverage tool you might find that you have a fairly low percentage of coverage.

What are the techniques used for test coverage?

Test Coverage Techniques You Should Know. With the basics out of the way, it’s finally time for us to dig deeper into our list of test coverage techniques: product coverage, risk coverage, requirements coverage, boundary-value coverage and AI-aided test automation.

Is code coverage enough?

What are code coverage techniques?

It helps you to measure the efficiency of test implementation. Five Code Coverage methods are 1.) Statement Coverage 2.) Condition Coverage 3) Branch Coverage 4) Toggle Coverage 5) FSM Coverage. Statement coverage involves execution of all the executable statements in the source code at least once.
