Question

My specs:

it "has empty thread" do
  Thread.current[:foo].should be_nil
  Thread.current[:foo] = "bar"
end

it "has empty thread" do
  Thread.current[:foo].should be_nil
end

Second spec fails because thread was changed by previous spec.
How can I run specs in different threads or ‘nullify’ thread’s keys before each spec or something else to pass second spec?

You can create the Thread in the spec ; don’t’ forget to join it to get the results of the should‘s from the thread re-evaluated:

it "has empty thread" do
    Thread.new {
        Thread.current[:foo].should be_nil
        Thread.current[:foo] = "bar"
    }.join
end

it "has empty thread" do
    Thread.new {
        Thread.current[:foo].should be_nil
    }.join
end
