microtest Build StatusDependency Status

Version 1.2.3

A very tiny testing framework inspired by minitest/minitest.cr.

Features

  • This framework is opinionated
  • It uses power asserts by default. There are no assert_equals, assert_xyz, just power asserts (except for assert_raises)
  • It uses the spec syntax for test case structure (describe, test, before, after). Reasons: No test-case name-clashes when using describe. Not forgetting to call super in setup/teardown methods.
  • No nesting of describe blocks. IMO nesting of those blocks is an anti-pattern.
  • No let-definitions. Only before / after hooks. Use local variables mostly.
  • Tests have to be started explicitly by Microtest.run!, no at-exit hook.
  • Colorized and abbreviated exception stacktraces

Installation

Add this to your application's shard.yml:

development_dependencies:
  microtest:
    github: ragmaanir/microtest
    version: ~> 1.2.3

And add this to your spec_helper.rb:

require "microtest"

include Microtest::DSL

Microtest.run!

Usage

describe MyLib::WaterPump do
  test "that it pumps water" do
    p = MyLib::WaterPump.new("main")
    p.enable
    p.start

    assert(p.pumps_water?)
  end

  test "that it pumps with a certain speed" do
    p = MyLib::WaterPump.new("main", speed: 100)
    p.enable
    p.start

    assert(p.pump_speed > 50)
  end

  test "this one is pending since it got no body"

  test "only run this focused test", :focus do
  end

  test! "and this one too since it is focused also" do
  end
end

Run the test with:

crystal spec

You can provide the seed to run the tests in the same order:

SEED=123 crystal spec

Power Assert Output

describe AssertionFailure do
  test "assertion failure" do
    a = 5
    b = "aaaaaa"
    assert "a" * a == b
  end
end

Generates:

[Assertion Failure](assets/assertion_failure.jpg?raw=true)

Reporters

Select the used reporters:

Microtest.run!([
  Microtest::DescriptionReporter.new,
  Microtest::ErrorListReporter.new,
  Microtest::SlowTestsReporter.new,
  Microtest::SummaryReporter.new,
] of Microtest::Reporter)

describe First do
  test "success" do
  end

  test "skip this"
end

describe Second do
  def raise_an_error
    raise "Oh, this is wrong"
  end

  test "first failure" do
    a = 5
    b = 7
    assert a == b * 2
  end

  test "error" do
    raise_an_error
  end
end

When focus active

describe Focus do
  test "not focused" do
  end

  test! "focused" do
  end

  test "focused too", :focus do
  end
end

[Focus](assets/focus.jpg?raw=true)

Development

I am using guardian to run the tests on each change. Also the guardian task uses the computer voice to report build/test failure/success. Run bin/build to run tests and generate README.md from README.md.template and generate the images of the test outputs (using an alpine docker image).

DONE

  • [x] hooks (before, after, around), and global ones for e.g. global transactional fixtures
  • [x] Customizable reporters
  • [x] Capture timing info
  • [x] Randomization + configurable seed
  • [x] Reporter: list N slowest tests
  • [x] assert_raises
  • [x] skip
  • [x] Write real tests for Microtest (uses JSON report to check for correct test output). Now tests are green.
  • [x] JSON reporter
  • [x] SummaryRepoter
  • [x] Continuous Integration with Travis
  • [x] focus
  • [x] generate README including examples from specs and terminal screenshots
  • [x] Print whether focus is active
  • [x] crtl+c to halt tests

TODO

  • [ ] fail fast
  • [ ] Number of assertions
  • [ ] Alternatives to nesting? (Use separate describe blocks)
  • [ ] Group tests and specify hooks and helper methods for the group only
  • [ ] save results to file and compare current results to last results, including timings

Problems

  • [ ] Some assertion failures cause segfaults
