The Sinatra of testing frameworks

Here's what MicroTest brings to the table.

Simplicity

A tiny API with only 4 methods.
You'll be up and running faster than ever before.

Only 1 Assert Method

Avoid the complexity in other test frameworks and focus on what really matters.

Pry Integration

Easily debug test failures with Pry for a more productive workflow.

Plays Nice

Runs side by side with other test frameworks which makes it easy to integrate into existing projects.

Random Run Order

Prevents the bad practice of run order dependencies by running tests in random order.

Customizable Output

Customize test output with pluggable formatters, or give back by writing your own.

Asynchronous Test Runs

Speed up your test suite with asynchronous test runs. Works with MRI, but your best results will be with JRuby or Rubinius.

The API has simplified a little to support this feature. Be sure to read up on the changes.

Try out async today.

$ gem install micro_test
$ mt --demo --async

Quick Start

1. Install

$ gem install micro_test

2. Write a test

require 'micro_test'
class MyTest < MicroTest::Test
  test "some assumption" do
    assert true
  end
end

3. Run tests
```
$ mt





            
```
4. View output
```
            
```

The Interface simple by design

`MicroTest::Test`	Superclass for all tests.
`test(desc, &block)`	Defines a test method. `desc` - a description of what is being tested `&block` - a block of code which defines the test
`assert(value)`	Verifies the truthiness of a value. `value` - the value to assert
`before(&block)`	A callback that runs before each test method. `&block` - the block of code to execute
`after(&block)`	A callback that runs after each test method. `&block` - the block of code to execute

Full Example

class MathTest < MicroTest::Test

  before do
    # runs before each test
  end

  test "addition" do
    assert 2 + 2 == 4
  end

  test "subtraction" do
    assert 2 - 2 == 0
  end

  test "multiplication" do
    assert 2 * 2 == 4
  end

  test "division" do
    assert 2 / 2 == 1 # add a trailing comment if you want a message
  end

  # and one failing test
  test "fail" do
    assert 2 + 2 == 5
  end

  after do
    # runs after each test
  end

end
