Adding a Test Name and Outcome to Your Test

You can enter a test name and select an outcome for your Live Tests after cross-browser and mobile app testing. Adding a name and outcome to your test allows you to add more context to test descriptions and add more clarity to your test repository.

You can use test names to customize your testing experience. For example you can:

• Add descriptive names to your tests to quickly identify your findings.
• Keep track of tested steps by adding details to test names.
• Rename your tests to reflect Jira tickets or other related tasks.

note

Test names are limited to 255 characters. The use of emojis is not supported in the test name.

• From the end session screen, you can select an outcome and enter a test name:

  • Start a Live Test session.
  • End the Live Test Session by clicking End on the toolbar.
  • On the test session end screen, select the test outcome and edit the test name.

• From the test details page, you can add or edit a test name:

  • Go to Live -> Test results
  • Click a test.
  • On the test details page, click the pencil next to the test name to edit it.
  • Enter a descriptive name for the test, for example:

Running Tests in Parallel

You can run multiple live test sessions at the same time, with the number of tests limited by the concurrency allowance associated with your account. To run tests in parallel, open a new browser tab and follow the steps to set up the new session. You can switch back and forth between the sessions by clicking on the browser tabs.

Time Limits and Timeouts for Cross Browser Testing

For VDC and EmuSIM, the global limitations for the live session duration are:

• Cross Browser tests for free users have an 11-minute limit from the session start.
• Cross Browser tests for paid users are limited to three hours.
• Cross Browser tests for all accounts will timeout after 90 seconds if the session is not active (that is, it has no active channels).

If there is no activity a user is automatically logged out after 30 min.

Troubleshooting Live Cross Browser Tests

Below are resolutions to common errors that you may experience in live cross browser testing.

Seeing a Security Error Message (Error #2048)

This error is displayed when the ports used by manual testing relies are being blocked by a firewall on your end. This may also be caused by running apps such as Avast! antivirus software.

Below are the servers and ports used by manual testing. If you plan to launch manual tests on locally installed browsers, we recommend checking with your network administrator to confirm that you can make secure websocket connections to: api.us-west-1.saucelabs.com:443 (for US-West-1 DC) or api.eu-central-1.saucelabs.com:443 (for EU-Central-1 DC).

Your Job is Not Loading

When a job is not loading, one of the following errors is likely to appear:

• Error message: "Uh oh! Some error occurred while connecting to the browser"
• The job seems to start, but you see only a white text box in the middle of a black screen.

Both errors indicate that your browser is having trouble displaying the VNC stream from the remote machine. Below are some steps to troubleshoot:

Check the Video on Sauce

If the recorded video after the job shows a steady video stream, this indicates that the issue is in your computer or connection to Sauce Labs. However, if the Sauce Labs video shows the same issue, that indicates an issue in our service. In that case, send us the URL for the job page and a screenshot of the issue.

Confirm That Your Browser is Up to Date

If you're on an older version, this may cause incompatibilities. Update your browser and try again.

Check Your Firewall

Make sure that your machine allows full access for the interactive stream over the required ports (see the Sauce Connect Proxy FAQ).

Confirm That Your Internet Connection is Stable

We recommend running Sauce tests from a machine with a wired Ethernet connection, to ensure a steady connection. If the connection flickers, this error could be thrown.

Long Load Times or Timing Out

We've streamlined our service to provide the best possible load times. If you're experiencing slow live testing sessions, head to the Sauce Labs Systems Status page and follow us on Twitter (@SauceOps) for the latest updates on service issues and operations.

Links Opening in New Tabs Instead of New Windows

It's possible for the manual testing VNC client to have a modifier key "stuck" down, causing any clicked links to open in new tabs. This happens if the client loses focus while a key is held down (for example, when using Alt-Tab to switch app windows). In this case, VNC never receives the keyUp event.

To prevent this from happening: every time you focus back on the manual testing window, click in the middle of the page, then press and release all the modifier keys (that is, Alt, Control, Command, and Shift).
