Test Annotation

Test annotation refers to adding information to your tests, such as a name, build number, tag, and pass/fail status. These annotations are useful for managing your tests and builds (for example, when searching and sorting tests in your Archives).

You can add annotations after test execution with our REST API or during test execution with the Selenium JavaScript Executor. You can also use sample test frameworks to automatically add annotations to your tests.

What You'll Need

Selenium JavaScript Executor

Selenium's JavascriptExecutor lets you use JavaScript commands in your test scripts to perform actions in the browser. We've developed a set of custom JavascriptExecutor methods you can use to annotate tests and record pass/fail status. You can also use these methods to track information in your Selenium log for debugging.

Basic Example

Here's a Java code sample setting a job's name to "My test":

((JavascriptExecutor)driver).executeScript("sauce:job-name=My test");



Appium JS-Executor methods for Real Device Testing in Sauce Labs are limited and are indicated with the following badge: RDC ✓

"sauce:job-result=passed" RDC ✓Sets the pass/fail status of the job. Options are passed, failed, true, and false. True means passed and false means failed.
"sauce:job-name=My awesome job" RDC ✓Sets the job name
"sauce:job-tags=tag1,tag2,tag3"Sets the job tags in a comma-separated list.
"sauce:job-build=mybuild123"Sets the job’s build name.
"sauce: stop network"
"sauce: start network"
Stops and restart the VM’s network connection (Mac OSX only).
"sauce: disable log"
"sauce: enable log"
Turns off logging for certain commands within the test in order to omit sensitive data from the log.json file; then re-enables logging.

NOTE: This method does not omit the commands from other possible records.

"sauce: break"Sets a Sauce breakpoint in the test. Test execution will pause at this point, waiting for manual control by clicking in the test’s live video.
"sauce:context=This line appears in the command list as 'info'"Logs the given line in the job’s Selenium commands list.
"sauce:job-info={'build':'mybuild','name':'my test name', 'public':'team}"Sets one or more job information fields to the values sent in the JSON-formatted dictionary.
"sauce:inject-image=[base64_encoded_image]" RDC ✓Points to file for testing image injection (e.g., barcode scanning).
"sauce:performanceEnable"Allows performance metrics to be collected.
"sauce:performanceDisable"Pauses performance metrics collection.

Spacing in the methods is sensitive, i.e., some methods require a space following sauce: (stop, start, disable, enable, break, and job-info), while other methods do not.

Setting Pass/Fail

Setting the pass/fail status of your tests is important for getting the most out of your insights, as Selenium has only three built-in states: In Progress, Error, and Complete.

You should update your tests to record pass/fail status with our REST API on completion, using a test framework, or the sauce:job-result method.

Code Example

This code is from a sample Java test script using TestNG. You can find the full version in our Test Frameworks repository.

* Method that gets invoked after test.
* Dumps browser log and
* Closes the browser


public void tearDown(ITestResult result) throws Exception {

//Gets browser logs if available.
((JavascriptExecutor) webDriver.get()).executeScript("sauce:job-result=" + (result.isSuccess() ? "passed" : "failed"));

Providing Context for Selenium Commands

One of the most difficult aspects of troubleshooting Selenium tests can be matching commands to browser actions. The sauce:context method provides you with a way to inject text into the command log to associate with a specific command, essentially adding a comment.

For example, in the command log on the left, it's hard to immediately see which command is responsible for following a link to the page, which one submitted a comment, and which one asserted that the comment was valid. In the screenshot on the right, each set of commands has been provided with a context.

Context for Selenium commands - beforeContext for Selenium commands - after

Code Example

In your script, assign a context with each step of the test is set using the sauce:context method.

The following code examples are from the Java-TestNG-Selenium framework in our GitHub repository.

* Method to be invoked after test.
* Dumps browser log and
* Closes the browser


public void tearDown(ITestResult result) throws Exception {

//Gets browser logs if available.
((JavascriptExecutor) webDriver.get()).executeScript("sauce:job-result=" + (result.isSuccess() ? "passed" : "failed"));

protected void annotate(String text) {
((JavascriptExecutor) webDriver.get()).executeScript("sauce:context=" + text);

In your test script, specify the text you want associated with each step of the test:

public class TextInputTest extends TestBase {

* Runs a simple test verifying if the comment input is functional.
* @throws InvalidElementStateException

@org.testng.annotations.Test(dataProvider = "hardCodedBrowsers")
public void verifyCommentInputTest(String browser, String version, String os, Method method)
throws MalformedURLException, InvalidElementStateException, UnexpectedException {
this.createDriver(browser, version, os, method.getName());
WebDriver driver = this.getWebDriver();

String commentInputText = UUID.randomUUID().toString();
this.annotate("Visiting GuineaPig page...");
GuineaPigPage page = GuineaPigPage.visitPage(driver);

this.annotate(String.format("Submitting comment: \"%s\"", commentInputText));

this.annotate(String.format("Asserting submitted comment is: \"%s\"", commentInputText));


Sauce Labs REST API

Virtual Devices Only

You can manage your tests more effectively from your Dashboard and Archives with annotations. The Sauce Labs REST API includes an update_job method that you can use to set a name, tags, pass/fail status, and custom data for your test after it runs. To automate test annotation with this method, you'll want to create a simple set of functions to perform the put request for you.

Sauce Labs REST API Examples
Adding Pass/Fail Status and Build Numbers to Test Results with Frameworks

In addition to using the REST API to set these annotations once your test completes, you can use one of the Sauce Labs test framework examples to set these and other annotations for you automatically as part of the test execution.

Desired Capabilities for Annotation

You can set the following test configuration options to keep track of your jobs:

OptionDescriptionKeyValue TypeExample
Test NamesUsed to record test names for jobs and make it easier to find individual testsnamestring"name" : "my example name"
Build NumbersUsed to associate jobs with a build number or app version, displayed on the Dashboard and Archives viewsbuildstring"build": "build-1234"
TaggingUser-defined tags for grouping and filtering jobs in the Dashboard and Archivestagslist"tags": ["tag1","tag2","tag3"]
Pass/Fail StatusSelenium and Appium handle sending commands to control a browser or app, but don't report to the server whether a test passed or failed. To record pass/fail status on Sauce, set the passed flag on the job.
Since you can't know in advance whether a test passed or failed, this flag can't be set in the initial configuration.
passedboolean"passed": "true"
Custom DataUser-defined custom data that will accept any valid JSON object, limited to 64KB in size.customDataobject"customData": {"release": "1.0", "commit": "0k392a9dkjr", "staging": true, "execution_number": 5, "server": ""}

"release": "1.0",
"s erver": ""

Use Build IDs, Tags, and Names to Identify Your Tests

By assigning unique attributes (such as test name, tags, and build ID) in your test capabilities, you can then apply these annotations to filter results on your Sauce Labs Test Results and Archive pages. Although not required, following this best practice can make it easier to monitor tests and builds in your CI pipeline.

You can set these capabilities to be any combination of letters and numbers. To differentiate between builds, it's also a good practice to add a timestamp or CI job/build number at the end of your build tag.


While it's technically possible to use the same build name for multiple test runs, this will cause all of your test results to appear incorrectly as part of a single run. This, in turn, will cause your test results for those builds to be inaccurate.

Code Examples: Build, Tags, and Name

String username = System.getenv("SAUCE_USERNAME");
String accessKey = System.getenv("SAUCE_ACCESS_KEY");
MutableCapabilities sauceOptions = new MutableCapabilities();
sauceOptions.setCapability("name", "Web Driver demo Test");
sauceOptions.setCapability("tags", "tag1");
sauceOptions.setCapability("build", "build-1234");
sauceOptions.setCapability("username", username);
sauceOptions.setCapability("accessKey", accessKey);

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setCapability("sauce:options", sauceOptions);
firefoxOptions.setCapability("platformName", "Windows 10");
firefoxOptions.setCapability("browserVersion", "79.0");
WebDriver driver = new RemoteWebDriver(new URL(""), firefoxOptions);
