Cucumber Clock steps for Golang

clockdog uses nhatthm/go-clock to provide steps for cucumber/godog and makes it easy to run tests with time.

Usage

Initiate the clock and register it to the scenario.

package mypackage

import (
	"testing"

	"github.com/cucumber/godog"
	"github.com/nhatthm/clockdog"
)

func TestIntegration(t *testing.T) {
	clock := clockdog.New()
	suite := godog.TestSuite{
		Name:                 "Integration",
		TestSuiteInitializer: nil,
		ScenarioInitializer: func(ctx *godog.ScenarioContext) {
			clock.RegisterContext(ctx)
		},
		Options: &godog.Options{
			Strict:    true,
			Output:    out,
			Randomize: rand.Int63(),
		},
	}
	
	// Inject the clock to your application then run the suite.
	status := suite.Run()
}

Steps

Set the time

By default, the clock always returns time.Now() unless you freeze or set it. For setting, you can use one of these:

• (?:the )?clock is at "([^"]*)"
• (?:the )?clock is set to "([^"]*)"
• sets? (?:the )?clock to "([^"]*)"
• now is "([^"]*)"

They have the same effect, the clock will be set at a specific time.Time. The given can be in RFC3339 (2006-01-02T15:04:05Z07:00) or YMD (2006-01-02)

For example:

    Scenario: Set time
        Given the clock is at "2020-01-02T03:04:05Z"
        Then the time is "2020-01-02T03:04:05Z"

        Given the clock is set to "2020-02-03T04:05:06Z"
        Then the time is "2020-02-03T04:05:06Z"

        Given Someone sets the clock to "2020-03-04T05:06:07Z"
        Then the time is "2020-03-04T05:06:07Z"

        Given now is "2020-04-05T06:07:08Z"
        Then the time is "2020-04-05T06:07:08Z"

Adjust the time

After setting the clock, you can adjust the time by adding a time.Duration, some days, months or years with these:

• adds? ([^\s]*) to (?:the )?clock
• adds? ([0-9]+) days? to (?:the )?clock
• adds? ([0-9]+) months? to (?:the )?clock
• adds? ([0-9]+) years? to (?:the )?clock
• adds? ([0-9]+) months?,? ([0-9]+) days? to (?:the )?clock
• adds? ([0-9]+) years?,? ([0-9]+) days? to (?:the )?clock
• adds? ([0-9]+) years?,? ([0-9]+) months? to (?:the )?clock
• adds? ([0-9]+) years?,? ([0-9]+) months?,? ([0-9]+) days? to (?:the )?clock

Important: You have to set the clock before adjusting it. Otherwise you will get clockdog.ErrClockIsNotSet

For example:

    Scenario: Add time
        Given the clock is at "2020-01-02T03:04:05Z"
        And someone adds 1h5s to the clock
        Then the time is "2020-01-02T04:04:10Z"

        Given someone adds 2 days to the clock
        Then the time is "2020-01-04T04:04:10Z"

Freeze and release the clock

    Scenario: Freeze and Release
        Given the time is now

        When I freeze the clock
        And I wait for 50ms
        Then the time is not now

        When I wait for 50ms
        And I release the clock
        Then the time is now
