Allure doesn't make a screenshot on a mobile device during the autotests with pyTest uiAutomator on Android

[nataly22]

When I run autotests with pytest+Selenium WebDriver+allure - allure makes screenshots,
but I run autotests with pyTest_uiAutomator+allure on mobile device Android - I get error when want to look png.file with screenshots.

My testcode:

@allure.feature('Autorization to  ...')
@allure.story('Autorization to ...')
    def test_autorization(self):
        ...
        time.sleep(4)
        d.press.home()
        ...
        #Make photo of start page
        allure.attach('my attach','Screen_start_page', allure.attach_type.PNG)

after that a have during open png file:: "Fatal error reading PNG image file: Not a PNG file"

@nataly22 could you please provide MVE and/or actual report (with source files and built reports)?

I wrote a reply with source files and built reports on gitHub site in my issue.

Thank you in advance for your help in solving the problem

@nataly22 however useful screenshots could be they fail to provide the most crucial information. Please attach a .tar.gz / .zip archive with the source code and reports to the github issue.

Apparently, you are doing screenshots wrong.

Contents of the attachment files are as follows:

pupssman@airship:~/Downloads $ cat ~/Downloads/3d95375c-d765-404a-9bf4-6c985832f0f2-attachment.png 
Screen_start_pagepupssman@airship:~/Downloads $ 

I.e. there is plain text string Screen_start_page instead of image data.

This may be caused by you explicitly commanding allure to attach that very plain text string in your code:

allure.attach('my attach','Screen_start_page', allure.attach_type.PNG)

As per allure's documentation, second argument to the allure.attach method call is the file content to be attached, which one would expect to be the PNG raw data in your case, instead of the plain text string found in the code.

This appears to be a simple typo in the test code and is therefore not a problem with the allure or allure plugin at all.

Please, be more careful with your code and good luck)

Thanks for the advice. The problem was solved as follows:

#We take screenshots by comand of uiautomator
d.screenshot('/home/ngora//reports/ui/myattach.png')
#open file as in python
f = open('/home/ngora//reports/ui/myattach.png')
#read files content to second parameter of attach method
allure.attach('Start2_page',f.read(), type=AttachmentType.PNG)
