Converts English to Automated browser tests

How do you use it?

Scenario: Seeing a welcome message!

Given I log in as “teacher”!

When I follow “My Course”!

Then I should see “Welcome to My Course”

Hundreds of “steps”

Given I turn editing mode on!

Given I create a course with:!

| fullname | shortname | format |!

| Math 101 | math101 | topic |!

Given I import “source” course into “destination” course

Demo

How does it work?Example: When I follow “My Course”!

/** * @When /^I follow "(?P<link_string>(?:[^"]|\\")*)"$/!

*/!

public function click_link($link) {!

$linknode = $this->find_link($link);!

$linknode->click();!

}!
