Testing on Different Browsers
Preflight uses global defaults to define on which browser to run your tests. However, these defaults can be overridden for individual tests, that may need to be run on more or fewer browsers. In addition, the defaults can be customized for a specific run only. Preflight supports the following browsers:
- Chrome
- Firefox
- Edge
- Internet Explorer
Defining the Default Browsers
To Define the Default Browsers:
- In the Navigation bar, select Settings > Browsers.
- Click the checkbox next to each browser you want to test by default.

Overriding the Default Browsers
The default settings can be overridden if you have tests you want to run on more or fewer browsers. For example, specific functionality that has had issues in the past, or core functionality you want to test more thoroughly.
To Override the Default Browsers:
-
In the Navigation bar, select Tests.
-
Select a test from the All Tests screen to open it.
-
Click Test Settings and then select Browsers.
-
Under Choose Browsers select the browsers you want to define for this test.
Note: To return to the original settings, click Use Global Defaults.
-
Click Save.
You can also change tests settings in bulk:
- In the Navigation bar, select Tests.
- Click the checkboxes next to the relevant tests from the All Tests page or from the Groups page.
- Select the browser(s) from the Browsers menu at the top of the page.
Note: To return to the original settings, select Use Global Defaults from the menu.
Defining Browsers On Demand
You can define a specific browser to test on-demand (one time only).
To Define Browsers On Demand:
- In the Navigation bar, select Tests.
- Select the tests you wish to test. To test all tests don't select any.
- Click the arrow next to Run All Tests and select Run All Tests with Custom Settings.
- In the Browsers section, select the browsers you want to test.
- Scroll down and click Run All\Selected Tests Now.
