In this tutorial, we will create some UI tests as Cucumber Scenario(s)/Scenario Outline(s) and use Cypress to implement the tests in JavaScript.
For the purpose of this tutorial, we'll use a dummy website (source-code here) containing just a few pages to support login/logout kind of features; we aim to test precisely those features.
Before moving into the actual implementation, we need to decide is which workflow we'll use: do we want to use Xray/Jira as the master for writing the declarative specification (i.e. the Gherkin based Scenarios), or do we want to manage those outside using some editor and store them in Git, for example?
Please see Testing in BDD with Gherkin based frameworks (e.g. Cucumber) for an overview of the possible workflows. The place that you'll use to edit the Cucumber Scenarios will affect your workflow. There are teams that prefer to edit Cucumber Scenarios in Jira using Xray, while there others that prefer to edit them by writing the .feature files by hand using some IDE. |
This section assumes using Xray as master, i.e. the place that you'll be using to edit the specifications (e.g. the scenarios that are part of .feature files).
The overall flow would be something like this:
Usually, you would start by having a Story, or similar (e.g. "requirement"), to describe the behavior of a certain feature and use that to drive your testing.
If you have it, then you can just use the "Create Test" on that issue to create the Scenario/Scenario Outline and have it automatically linked back to the Story/"requirement".
Otherwise, you can create the Test using the standard (issue) Create action from Jira's top menu.
In this case, we'll create a Cucumber Test, of Cucumber Type "Scenario".
We can fill out the Gherkin statements immediately on the Jira issue create dialog or we can create the Test issue first and fill out the details on the next screen, from within the Test issue. In the latter case, we can take advantage of the built-in Gherkin editor which provides auto-complete of Gherkin steps.
After the Test is created it will impact the coverage of related "requirement", if any.
The coverage and the test results can be tracked in the "requirement" side (e.g. user story). In this case, you may see that coverage changed from being UNCOVERED to NOTRUN (i.e. covered and with at least one test not run).
The related statement's code is managed outside of Jira and stored in Git, for example.
In Cypress, tests related code is stored under cypress/integration
directory, which itself contains several other directories. In this case, we've organized them as follows:
cypress/integration/common
: step implementation files, in JavaScript.import { Given, When } from 'cypress-cucumber-preprocessor/steps'; import LoginPage from '../../pages/login-page'; import LoginResultsPage from '../../pages/login-results-page'; Given(/^browser is opened to login page$/, () => { LoginPage.visit(); }); When('user {string} logs in with password {string}', (username, password) => { LoginPage.enter_username(username); LoginPage.enter_password(password); LoginPage.pressLogin(); }); Then(/^welcome page should be open$/, () => { LoginResultsPage.expect().toBeSuccessful(); }); Then(/^error page should be open$/, () => { LoginResultsPage.expect().toBeUnsuccessful(); }); |

cypress/integration/pages
: abstraction of different pages, somehow based on the page-objects modelimport LoginResultsPage from './login-results-page'; const USERNAME_FIELD = 'input[id=username_field]'; const PASSWORD_FIELD = 'input[id=password_field]'; const LOGIN_BUTTON = 'input[type=submit]'; const LOGIN_TEXT = 'LOGIN'; class LoginPage { static visit() { cy.visit('/'); } static enter_username(username) { cy.get(USERNAME_FIELD) .type(username); } static enter_password(password) { cy.get(PASSWORD_FIELD) .type(password); } static pressLogin() { cy.get(LOGIN_BUTTON).contains(LOGIN_TEXT) .click(); return new LoginResultsPage(); } } export default LoginPage; |

const RESULT_HEADER = 'h1'; class LogoutResultsPage { static expect() { return { toBeSuccessful: () => { cy.get(RESULT_HEADER).should('have.text', 'Login Page') }, }; } } export default LogoutResultsPage; |

cypress/integration/login
: Cucumber .feature files, containing the tests as Gherkin Scenario(s)/Scenario Outline(s)@REQ_CALC-7905 Feature: As a user, I can login the applicaiton Scenario: Valid Login Given browser is opened to login page When user "demo" logs in with password "mode" Then welcome page should be open Scenario: Invalid Login Given browser is opened to login page When user "dummy" logs in with password "password" Then error page should be open Scenario Outline: Login With Invalid Credentials Should Fail Given browser is opened to login page When user "<username>" logs in with password "<password>" Then error page should be open Examples: | username | password | | invalid | mode | | demo | invalid | | invalid | invalid | |
@REQ_CALC-7906 Feature: As a user, I can logout the application Scenario: Valid Logout Given user is on the welcome page When user chooses to logout Then login page should be open |
You can then export the specification of the test to a Cucumber .feature file via the REST API, or the Export to Cucumber UI action from within the Test/Test Execution issue or even based on an existing saved filter. A plugin for your CI tool of choice can be used to ease this task.
So, you can either:
#!/bin/bash curl -u admin:admin "http://192.168.56.102/rest/raven/1.0/export/test?keys=CALC-4763&fz=true" -o features.zip rm -f features/*.feature unzip -o features.zip -d features |
After being exported, the created .feature(s) will contain references to the Test issue key and the covered "requirement" issue key, if that's the case. The naming of these files is detailed in Export Cucumber Features.
@REQ_CALC-7895 Feature: As a user, I can calculate the sum of 2 numbers # Addition is great as a verification exercise to get the Cucumber-js infrastructure up and running @TEST_CALC-4763 @features/addition.feature Scenario: Add two number Given the numbers 2 and 3 When they are added together Then should the result be 5 |
To run the tests and produce a Cucumber JSON report, we can use the cucumber-js
binary.
./node_modules/cucumber/bin/cucumber-js -f json:report.json |
After running the tests, results can be imported to Xray via the REST API, or the Import Execution Results action within the Test Execution, or by using one of the available CI/CD plugins (e.g. see an example of Integration with Jenkins).
curl -H "Content-Type: application/json" -X POST -u admin:admin --data @"report.json" http://jiraserver.example.com/rest/raven/1.0/import/execution/cucumber |
To import results, you can use two different endpoints/"formats" (endpoints described in Import Execution Results - REST):
The standard cucumber endpoint (i.e. /import/execution/cucumber) is simpler but more restrictive: you cannot specify values for custom fields on the Test Execution that will be created. This endpoint creates new Test Execution issues unless the Feature contains a tag having an issue key of an existing Test Execution. The multipart cucumber endpoint will allow you to customize fields (e.g. Fix Version, Test Plan), if you wish to do so, on the Test Execution that will be created. Note that this endpoint always creates new Test Executions (as of Xray v4.2). In sum, if you want to customize the Fix Version, Test Plan and/or Test Environment of the Test Execution issue that will be created, you'll have to use the "multipart cucumber" endpoint. |
A new Test Execution will be created (unless you originally exported the Scenarios/Scenario Outlines from a Test Execution).
The execution screen details of the Test Run will provide overall status information and Gherkin statement-level results.
Results are reflected on the covered item (e.g. Story). On its issue screen, coverage now shows that the item is OK based on the latest testing results, that can also be tracked within the Test Coverage panel bellow.
