preface

Assumptions is a collection of utility methods that support conditional test execution based on assumptions.

In direct contrast to failed assertions, failed assumptions do not result in a test failure; rather, a failed assumption results in a test being aborted.

project description

It is often very handy to exclude some tests from running on CI - for example - we don't want to run tests that creates files (for example - there are no permissions to create files on Travis server).

The easiest configuration will be:

var file = new File("file.txt");

assumingThat(() -> !Objects.equals(System.getProperty("user.name"), "travis"),
        () -> assertTrue(file.createNewFile()));

file.delete();
