"useDefaultBrowserType" property leads to "no tests were found"

[theBaldSoprano]

Describe the bug We set useDefaultBrowserType to true expecting preset to use default browser from playwright's deviceDescriptorsSource.json file. When running - we don't get any errors, but run passes with "no tests were found" message skipping all tests.

In general our intention is to use devices (playwright's or custom) with useDefaultBrowserType turned ON and do not specify any browser.

Also it seems like preset is bugging only with devices which have webkit or firefox set as default browser coz devices: ['Galaxy S8'] + useDefaultBrowserType: true seems to work fine.

To Reproduce

1. specify configuration options via Jest's testEnvironmentOptions option in jest.config.js file
2. add devices which have firefox or webkit defaults e.g. devices: ['JioPhone 2', 'iPhone XR']
3. do not specify browsers option
4. set useDefaultBrowserType to true
5. launch test

Expected behavior Test will be run two times:

1. in firefox on JioPhone 2
2. in webkit on iPhone XR

Additional context

• we tried to investigate jest-playwright-preset/lib/PlaywrightEnvironment.js file, especially line 170 but had no luck
• using DEBUG=pw:api; or/and PWDEBUG=1 doesnt output any additional info
• when specifying browsers and devices explicitly - all works fine
• bug is not related to testMatch option
