Stryker Mutator

Stryker is a mutation testing framework for JavaScript, C# and Scala

The Stryker mutation testing framework supports multiple programming languages, such as JavaScript, TypeScript, C#, Scala, and PHP.

Stryker modifies the source code and runs the test suite against each mutant. The framework can also run tests in parallel, speeding up the mutation testing process by utilizing multiple CPU cores.

It offers a variety of mutation operators, such as logical, string, array, and statement mutations. Stryker generates HTML reports that show the mutation score and the status of each mutant.
