Test utility to minimise code duplication for repetitive test cases.
test_in_case #
A dart test utility for creating variations of the same test using multiple cases. Write the testing logic once and provide a list of cases to test. Inspired by jest-in-case.
Installation #
dart pub add test_in_case --dev
OR
flutter pub add test_in_case --dev
Usage #
Import the test_in_case package. Use the cases function to define the tests. It takes in three parameters:
- title: The title of the group of tests.
- cases: A list of
TestCase
objects. - tester: Pass a the testing logic as a callback which will be called for each test case. The test case object is passed to the callback as an argument.
Call the cases function with a type parameter(cases<T>
), which will be used
as the type of the test case in the TestCase
object.
import 'package:test_in_case/test_in_case.dart';
cases<int>(
title: 'Even Numbers'
cases: [1, 2, 3]
.map(
(number) => TestCase(
name: '$number is even',
testCase: number,
),
)
.toList(),
tester: (testCase) => expect(testCase % 2 ==0, true);
);
