fixture `New Fixture`
.page `path/to/app`;
test(`New Test`, async t => {
await t.debug();
});
TestCafe version
1.20.1-rc.2
Command-line arguments
testcafe chrome test.js
I raised a similar issue that I guess would be the same as this one.. Is this being actively looked into for resolution? What's the current status?
No updates yet. Once we get any results, we will post them in this thread.

Hi folks,
TestCafe runs tests using the URL-rewritten proxy.
This approach is good. However, there is a way to improve the stability and speed of test execution - the native browser automation API.
We have a test execution mode uses native browser automation - we call it the Proxyless mode.
In Proxyless mode, a few issues are already fixed.
By the way, this issue was also fixed in Proxyless mode.
Try running your tests in Proxyless mode and let us know the results.
This option is available in all interfaces:
// Command-line
testcafe chrome tests --experimental-proxyless
// Programmatic
const testcafe = await createTestCafe({ experimentalProxyless: true });
// Configuration file
{
"experimentalProxyless": "true"
}
Note that at present it is an experimental mode.
Also, the Proxyless mode is implemented only in Google Chrome. It will not work correctly if you run tests in a non-Chrome browser or in a combination of other browsers.
