Cake

The tiniest unit tester, ported to Ruby

How to write unit tests

• Cake will search for anything that has .cake.rb for the file name in the directory that it's run in
• Example of how to write unit tests:

require_relative 'cake'

TestRunner.new('Test Runner - Basic', [
  Group.new('Group Basic', [
    Test.new(
      'True should be true',
      action: ->(test) {
              value = 'foo'
              test.actual = value
              test.expected = value
            },
      assertions: ->(test) { [Expect::Equals.new(actual: test.actual, expected: test.expected)] }
    )
  ])
])

You can also pass variables from parents and test stages.

  Group.new('Groups can assign context', [
    Test.new(
      'Group can pass context to children',
      assertions: ->(test) { [Expect::Equals.new(actual: test.foo, expected: 'bar')] }
    ),
    Test.new(
      'Children can override parent context',
      action: ->(test) { test.foo = 'baz' },
      assertions: ->(test) { [Expect::Equals.new(actual: test.foo, expected: 'baz')] }
    )
  ], setup: ->(test) {
    test.foo = 'bar'
  }),

Expect Matches

• Equals
• IsNotEqual
• IsNil
• IsNotNil
• IsTrue
• IsFalse
• RespondTo
• Undefined
• DoesNotRespondTo (synonym for Undefined)

How to run the test runner

• The package will need to run globally. Install via this command: gem install cake-tester
• After it's installed, you can run it by using cake-tester in the directory that you want to run your tests in. It will search any files in the directory or any sub-folders ending with cake.rb.
• You can also add flags to run specific tests or view output from specific tests.

Flags

File name filter

• -f [fileName]
  • Filters tests based off of file name
  • EX: cake-tester -f foo will test 'test-foo.cake.rb'

Verbose mode

• -v or --verbose
  • Displays full output of summary and tests run

Test Filter

• -t [testFilter], --tt [testFilter], --tte [testName], --tg [groupFilter], --tge [groupName], --tr [testRunnerFilter], --tre [testRunnerName]
  • All of these do similar things, which filters based off of title of the item. You can also use certain tags to run only a group, test runner, or a specific test.
  • Note - search is case-sensitive.
  • Examples:
    • -t General search: ruby cake-tester -t foo - Run all tests, groups, and runners with "foo" in the title
    • --tt Test search ruby cake-tester --tt "cool test" - Run all tests with the phrase "cool test" in the title
    • --tte Test search, exact: ruby cake-tester --tte "should only run when this one specific thing happens" - Runs only the test that matches the phrase exactly.
    • --tg Group search ruby cake-tester --tg bar - Run all groups matching "bar" in the title
    • --tge Group search, exact: `ruby cake-tester --tge "API Endpoints" - Runs all groups exactly matching the phrase "API Endpoints"
    • --tr Test Runner search: `ruby cake-tester --tr "Models" - Runs all test runners with "Models" in the title
    • --tre Test Runner search, exact: ruby cake-tester --tre "Models - User" - Runs test runners that exactly match the phrase "Models - User"

Interactive mode

• -i
  • Allows for repeatedly running tests. You can also use the test filters similar to non-interactive mode's syntax.
  • Note this is not yet implemented with this version.
