testify

scalable Flutter testing framework

declaratively create test cases and easily run them

specify virtually any test case for a testable unit by ...

• specifying unit type parameter T inside TestCase
• add a test description
• provide an assembler "builder" function and return the unit
• act on the unit and return it
• assert unit with usual test utility

DECLARE LIST OF TestCases

List<TestCase<Counter>> testCaseList = [
    TestCase<Counter>(
      description: 'properly increments the counter',
      assembler: () => Counter(),
      actors: [
        (counter) {
          counter.increment();
          return counter;
        },
      ],
      matchers: [
        (counter) {
          expect(counter.count, equals(1));
        }
      ],
    ),
    TestCase<Counter>(
      description: 'properly decrements the counter',
      assembler: () => Counter(),
      actors: [
        (counter) {
          counter.decrement();
          return counter;
        },
      ],
      matchers: [
        (counter) {
          expect(counter.count, equals(-1));
        }
      ],
    ),
  ];

RUN TestCase LIST WITH TestCaseExecutor

var testCaseExecutor = TestCaseExecutor(testCaseList);
testCaseExecutor.run();
