Screenshots are crashing testcafe

[franciscolosardo]

What is your Test Scenario?

When using the screenshot option running on a jenkins pipeline with saucelabs provider the following occurs.
When a test fails the following message is displayed multiple times and the test finally crashes. Testcafe exits with an error.

Error: [saveScreenshot("/OURJENKINSDOCKERDIR/screenshots/2019-10-22_17-03-12/test-1/Chrome_75.0.3770_Windows_10.0.0/errors/1.png")] ENOENT: no such file or directory, open '/OURJENKINSDOCKERDIR/screenshots/2019-10-22_17-03-12/test-1/Chrome_75.0.3770_Windows_10.0.0/errors/1.png'

This started happening without any change to our running instance and everything worked fine before. It even included the screenshot it took on our allure report.

Your Environment details:

• testcafe version: 1.6.0
• node.js version: v10.16.3
• command-line arguments:
• browser name and version: Chrome 76 @ Saucelabs
• platform and version: Win 7
• other: We are using the saucelabs browser provider

Hi @franciscolosardo

As I see, your environment is very complex: Jenkins, docker, SauceLabs, a custom Allure report.
It's difficult to set up the same environment on my side.
Try to debug the TestCafe yourself. You can use this as a starting point: https://github.com/DevExpress/testcafe/blob/b9c73f0823b0b15d35fc21b5796c8ac4c2ce55bd/src/browser/provider/built-in/dedicated/chrome/cdp.ts#L88.

I can confirm this issue when I run a test via testcafe-browser-provider-saucelabs locally or on CI the test fails on the following error

When I run the same test locally against chrome I don't get the error and a screenshot is saved as expected.

testcafe: 1.6.0
testcafe-browser-provider-browserstack: 1.9.0
node: v10.16.3

After investigation the problem is related to a non-existing folder being part of the path where to save the screenshot

e.g.

// in case "screenshots" does not exist
./tmp/

`<tescafecommand> -s ./tmp/screenshots`

ERROR

// in case "screenshots" does exist 
./tmp/screenshots/

`<tescafecommand> -s ./tmp/screenshots`

SUCCESS

We made sure to create the folder screenshots where screenshots are stored , but even when making the folders respectively we still get this error.
Note we are creating screenshots folder but not the subfolders that testcafe should create using the path prefix...
We even tried removing this prefix to see if using just a folder without folder patterns it worked, but i didn't

I was able to reproduce the issue with the following command: testcafe "saucelabs:Chrome@76.0:Windows 10" D:\Projects\testcafe\test\functional\fixtures\regression\gh-199 4\testcafe-fixtures\index.js -s path=screens/tmp/notexists/notexists/notexists
