Generate fast deterministic screenshots during Android instrumentation tests

screenshot-tests-for-android is a library that can generate fast deterministic screenshots while running instrumentation tests on Android. We mimic Android's measure(), layout() and draw() to generate screenshots on the test thread. By not having to do the rendering on a separate thread we have control over animations and handler callbacks which makes the screenshots extremely deterministic and reliable for catching regressions in continuous integration. We also provide utilities for using screenshot tests during the development process. With these scripts you can iterate on a view or layout and quickly see how the view renders in a real Android environment, without having to build the whole app. You can also render the view in multiple configurations at one go. 

CATS is a REST API Fuzzer and negative testing tool for OpenAPI endpoints. CATS automatically  generates, runs and reports tests with minimum configuration and no coding effort. Tests are self-healing and do not require maintenance.

By using a simple and minimal syntax, with a flat learning curve, CATS (Contract Auto-generated Tests for Swagger) enables you to generate thousands of API tests within minutes with no coding effort. All tests are generated, run and reported automatically based on a pre-defined set of 89 Fuzzers. The Fuzzers cover a wide range of input data from fully random large Unicode values to well crafted, context dependant values based on the request data types and constraints. Even more, you can leverage the fact that CATS generates request payloads dynamically and write simple end-to-end functional tests. 

EvoSuite - automated generation of JUnit test suites for Java classes

EvoSuite automatically generates JUnit test suites for Java classes, targeting code coverage criteria such as branch coverage. It uses an evolutionary approach based on a genetic algorithm to derive test suites. To improve readability, the generated unit tests are minimized, and regression assertions that capture the current behavior of the tested classes are added to the tests.
