Open Source Java Performance Testing Software for Linux

Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed. There’s also a cross-platform stand-alone executable for teams not comfortable with Java. You don’t have to compile code. Just write tests in a simple, readable syntax, carefully designed for HTTP, JSON, GraphQL and XML. And you can mix API and UI test-automation within the same test script. A Java API also exists for those who prefer to programmatically integrate Karate’s rich automation and data-assertion capabilities. It is worth pointing out that JSON is a ‘first class citizen’ of the syntax such that you can express payload and expected data without having to use double-quotes and without having to enclose JSON field names in quotes.

Performance test engine written in Java and exposed as a fluent API for writing JUnit tests. Perftence can also be used without JUnit by using perftence-api distribution package. Full test results are provided in html, which can published directly with different CI's (e.g. Jenkins/Hudson). Runtime test statistics are also provided through logging (e.g. using slf4j-log4j and log4j). Pertence tool can also be used for finding out threading issues. Just write a test that uses the component you need to test for threading issues and assign load of threads to the test. Thanks to my employer (Nokia) for letting me publish the initial version of this tool as open-source!
