Broadly speaking, it can be used to automate acceptance “test cases” (i.e. scripts) no matter the moment you decide to do so or the practices your team follows even though it's preferable to do it at start, involving the whole team in order to pursue shared understanding.
In this article, we will specify some tests using Robot Framework and see how we can have visibility of the corresponding results in Jira, using Xray.
This tutorial explores the specific integration Xray provides for Robot Framework XML reports.

The full ATDD workflow
In this example we're going to validate a dummy website (provided in the GitHub repository), checking for valid and invalid logins.
You may find the full source for this example in this GitHub repository, which corresponds in essence to previous work by Pekka Klärck from the Robot Framework Foundation.
If the team is adopting ATDD and working collaboratively in order to have a shared understanding of what is going to be developed, why and some concrete examples of usage, then the flow would be something similar to the following diagram.
All starts with a user story or some sort of “requirement” that you wish to validate. This is materialized as a Jira issue and identified by the corresponding issue key (e.g. ROB-11).
We can promptly check that it is “UNCOVERED” (i.e. that it has no tests covering it, no matter their type/approach).
A Test Plan can be created to define the scope of the testing that we aim to perform, group, and consolidate the corresponding results. Besides the user story, we may also add the Test Plan to the Board and assign it explicitly to a sprint. This will increase visibility of testing progress and help closing the gap between dev<>testers.
A tester/SDET could simply focus on implementing the automated test cases:
- The tester would write one or more test suites and corresponding test cases, using his/her favorite tool/IDE
- Each test case could be linked to the corresponding requirement/user story in Jira by adding its key as a tag
- Tests could then be run locally, or from the CI pipeline
- Unique, non-duplicating, Test entities would be auto-provisioned in Xray, corresponding to each test case; tester could also, optionally, enforce the result to an existing Test entity by specifying its issue key as a tag
Let’s take the following .robot file as an example, which acts as a suite containing one test case.
The previous Robot file uses a common resource that contains some generic variables and some reusable "keywords" (i.e., steps).
Running the tests can be done from the command line or from within Jenkins (or any other CI tool); this will produce a XML based report (e.g. output.xml).
Examples of running tests from the command line
Running tests is primarily done using the "robot" utility which provides many options that allow you to define which tests to run, the output directory and more.
You may also specify some variables and their values.
Next follows some different usage examples.
If you're using Python:
If you're using Java:
An unstructured (i.e. "Generic") Test issue will be auto-provisioned the first time you import the results, based on the name of the test case and of the corresponding test suites.
If you maintain the test case name and the respective test suites, the Test will be reused on subsequent result imports. You may always enforce the results to be reported against an existing Test, if you wish so: just specify its issue key as a tag.
Tags can also be used to cover an existing requirement/user story (e.g. “ROB-11”): when a requirement issue key is given, a link between the test and the requirement is created during the results import process.
Otherwise, tags are mapped as labels on the corresponding Test issue.
Note that Robot Framework considers the base folder of the project as the first test suite. The way you run your tests also affects Robot's XML; so, if you execute the file from somewhere else or you execute the file directly by passing it as an argument, the test suite's information will potentially be different.
A Test Execution will be created containing results for all test cases executed. In this case, you can see that it is also linked back to an existing Test Plan where you can track the consolidated results from multiple "iterations" (i.e. Test Executions).
Within the execution screen details, accessible from each row, you can look at the Test Run details which include the overall result and also specifics about each keyword, including duration and status.
Attaching screenshots at the step level is possible by using the SeleniumLibrary RF library. A configuration must be provided to embed the screenshots on the output.xml report; it can also be configured to take screenshots automatically on failed steps.
Example of including and initializing the SeleniumLibrary:
After importing the generated test report, we can see the screenshot in the Test Run details, in this case on the failed step.
Running tests in parallel, against different environments
In this distinct and more evolved example we're going to run tests in parallel using "pabot"; we'll also take advantage of the Test Environments concept provided by Xray.
This example uses a fake travel agency site (kindly provided by BlazeMeter) as the testing target.
We have two tests that use low-level keywords (note: this is not a good practice; it's just for simplicity) and one of those keywords is defined within a SeleniumLibrary plugin (i.e. it extends the keywords provided by SeleniumLibrary).
Running the tests in parallel is possible using pabot.
Tests can be parallelized in different ways; we'll split them for running on a test basis.
We can also specify some variables; in this case, we'll use it to specify the "BROWSER" variable which is passed to the SeleniumLibrary.
Running these tests will produce a report per each "argumentfileX" parameter (i.e. per each browser). We can then submit those to Xray (e.g. using "curl" and the REST API), and assign it to distinct Test Executions where each one is in turn assigned to a specific Test Environment identifying the browser.
In Xray, at the Test Plan-level we can see the consolidated results and for each test case we may drill-down and see all the runs performed and in which environment/browser.
In this case, we have the total of 4 Test Executions (i.e. for safari, headlessfirefox, chrome, firefox).
Tracking automation results
Besides tracking automation results on the Test Execution issues themselves, it's also possible to track in different places so the team gets fully aware of them.
On the user story issue screen
Right from within the user story issue screen, we now see one test (i.e. automated script) covering it. We can also see its latest result and how it impacts the overall coverage calculation for the user story; if the user story shows as “OK”, you know that all tests covering it passed, accordingly with the latest results obtained for each one of them.
On the Test Plan
At the Test Plan-level, the entity that defines the scope of testing and tracks its progress, we can quickly assess the latest consolidated test results (i.e. the latest result obtained for each Test being tracked).
