Parameterized test

Simple package that helps with executing parameterized tests. Inspired by JUnit ParameterizedTest CsvValues. This package is a wrapper around groups and test.

Features

This package helps executing a test multiple times with different parameters. Currently parameters can be specified as:

• ParameterizedSource.csv
• ParameterizedSource.value
• ParameterizedSource.values

When using ParameterizedSource.csv the library tries to parse the values to int, double, bool or String?. If the csv value contains a empty string it will be parsed to null. This parsing can be escaped by wrapping in the values in ' or ".

For example:

Input	Output
'banana, 4, apple'	'banana', 4, 'apple'
'banana, 4, '	'banana', 4, null
'banana, "4", apple'	'banana', '4', 'apple'
'banana, 4, """'	'banana', 4, ''

Getting started

Include the package in your project.

Usage

Instead of using groups or test you can now use parameterizedTest and supply it with multiple test parameters.

Csv source example:

parameterizedTest(
  'Amount of letters',
  ParameterizedSource.csv([
    'kiwi, 4',
    'apple, 5',
    'banana, 6',
  ]),
  (List<dynamic> values) {
    final String input = values[0];
    final expected = values[1];

    final actual = input.length;

    expect(actual, expected);
  },
);

Values source example:

  parameterizedTest(
    'Amount of letters',
    ParameterizedSource.values([
      ['kiwi', 4],
      ['apple', 5],
      ['banana', 6],
    ]),
    (List<dynamic> values) {
      final String input = values[0];
      final expected = values[1];

      final actual = input.length;

      expect(actual, expected);
    },
  );

Additional information

Its just a simple wrapper to easily execute tests multiple times with different values. Feel free to leave some feedback or open an pull request :)
