How do I increase my code coverage percentage?

Improving Test Coverage

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 many test cases are needed for coverage?

Condition coverage checks if both the outcomes(“true” or false”) of every condition have been exercised. The outcome of the decision point is only relevant for checking the conditions. It requires two test cases per condition for two outcomes.

How do you get 100 percent test coverage?

How Do You Ensure Test Coverage Is Good?

1. Create a comprehensive testing strategy.
2. Create a checklist for all of the testing activities.
3. Prioritize critical areas of the application.
4. Create a list of all requirements for the application.
5. Write down the risks inherent to the application.
6. Leverage test automation.

Can we achieve 100\% code coverage?

Realistically, there is no way you can complete a full set of mutation tests on a large software project in one run. So, your best bet is a compromise. Try to increase code coverage with your tests, but concentrate on tests that pass mutation testing.

How can I improve my test coverage?

4 Steps to Improve Your Test Coverage

1. What is Test Coverage? Test coverage measures how much of your application you test.
2. #1 Create a Plan and Set a Goal.
3. #2 Increase Code Coverage.
4. #3 Enhance Test Automation.
5. #4 Test on a Larger Scale.
6. Bonus: Increase Test Coverage by Running Tests with a Cloud Test Service.

How do you write test cases for code coverage?

You simply take:

1. (A) the total lines of code in the piece of software you are testing, and.
2. (B) the number of lines of code all test cases currently execute, and.
3. Find (B divided by A) multiplied by 100 – this will be your test coverage \%.

How do you write test coverage?

To calculate test coverage, you need to follow the below-given steps:

1. Step 1) The total lines of code in the piece of software quality you are testing.
2. Step 2) The number of lines of code all test cases currently execute.
3. For example:

How do I improve sonar code coverage?

So we would recommend tracking progress by:

1. Setting a Coverage on New Code requirement in your Quality Gate. The built-in, Sonar way Quality Gate requires 80\% and I think that’s a good place to start.
2. Strictly enforce your quality gate.
3. Sit back and watch your overall coverage gradually increase.

How do I increase code coverage in Python?

Increase coverage by adding more tests The code coverage has increased to 78\% on adding another test case. It can be increased further to 100\% in a similar fashion.

How many test cases are required to ensure code coverage as well as Decision Coverage?

Therefore, to achieve 100\% decision coverage, a second test case is necessary where A is less than or equal to B which ensures that the decision statement ‘IF A > B’ has a False outcome. So one test is sufficient for 100\% statement coverage, but two tests are needed for 100\% decision coverage.

How can I increase the coverage of my code?

Fundamentally, to increase your code coverage, you must write functional unit tests for code paths that are not currently covered. For more community resources on writing high quality unit tests, please see this canonical question; read the rest of this question to learn about common coverage scenarios.

How is code code coverage determined?

Code coverage is primarily performed at the unit testing level. Unit tests are created by developers, thus giving them the best vantage from which to decide what tests to include in unit testing. At this point, a number of questions arise: Are there enough tests in the unit test suite?

Is CoDecode coverage a misleading metric?

Code Coverage is a misleading metric if 100\% coverage is your goal (instead of 100\% testing of all features). You could get a 100\% by hitting all the lines once. However you could still miss out testing a particular sequence (logical path) in which those lines are hit.

How to improve code coverage by writing missing tests?

Typically, if you use a Continuous Integration tool, you can run code coverage against all your code. The result of this operation will give you an excellent insight into the status quo. Your team can then create a plan of action, allowing them to improve code coverage by writing missing tests.
