opal-spec
opal-spec is a minimal spec lib for opal, inspired by RSpec and MSpec. It is designed to run on opal, and provides the bare minimum to get specs running.
Writing Specs
Your specs should go into the /spec
directory of your app. They take
the same form as rspec/mspec:
describe MyClass do
it 'should do some feature' do
1.should == 1
end
it 'does something else' do
nil.should be_nil
false.should be_false
true.should be_true
end
end
Supported notations
* describe "foo" do ... end
* it "should foo" do ... end
* before do ... end
* after do ... end
* let(:foo) { ... }
* async # see below
* obj.should == other
* obj.should != other
* obj.should be_nil
* obj.should be_true
* obj.should be_false
* obj.should be_kind_of(klass)
* obj.should eq(other) # compare with :==
* obj.should equal(other) # compare with :equal?
* obj.should raise_error
* obj.should be_empty
* obj.should respond_to(method)
* obj.should_not xxx
```
### Async examples
Examples can be async, and need to be defined as so:
```ruby
describe 'MyClass' do
# normal, sync example
it 'does something' do
#...
end
# async example
async 'does something else too' do
#...
end
end
```
This just marks the example as being async. To actually handle the async
result, you also need to use a `run_async` call inside some future handler:
```ruby
async 'HTTP requests should work' do
HTTP.get('users/1.json') do |response|
run_async {
response.ok?.should be_true
}
end
end
```
The end of the block passed to `run_async` informs opal-spec that you are
done with this test, so it can move on.
