picotest

A tiny test framework for Crystal.

Features

• No Object class pollution
• No global macro
• Without closure overhead
• Support assert, reject, assert_raise, reject_raise basic assertions.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     picotest:
       github: firejox/picotest
   

2. Run shards install

Usage

Add this into spec then Run with crystal spec

require "picotest"

Example Code

PicoTest.spec do
  describe "example spec" do
    it "assert true == true" do
       assert true == true
    end

    it "reject true == false" do
      reject true == false
    end

    describe "nest spec" do
      it "catch raise" do
        assert_raise(Exception) do
          raise "OH NO!"
        end
      end

      it "no raise in block" do
        reject_raise do
          "it is safe"
        end
      end
    end

    pending "pending test"

    pending "pending with block" do
    end
  end
end

Before/After Hook

# The execution order is A -> D -> F -> E -> B
PicoTest.spec do
  describe "context" do
    before do
      # A
    end

    after do
      # B
    end

    describe "nested context" do
      before do
        # D
      end

      after do
        # E
      end

      it "F" do
      end
    end
  end
end

Async Spec

By default, each spec will run synchronously. You can make the spec run concurrently by setting sync: false. For example,

# A
PicoTest.spec sync: false do
  describe "Spec A" do
    it "run asynchronously" do
      # do something
    end
  end
end

# B
PicoTest.spec sync: false do
  describe "Spec B" do
    it "run asynchronously" do
      # do other thing
    end
  end
end

A and B will run concurrently.

Development

• before, after hooks
• report duration of spec
• run spec unit parallel in MT mode
• tag on test cases
• power assert support
