RobotFramework / Selenium: How to set screenshot-name to testcase-name on failure - selenium

Question

I was wondering if there is a possibility to make the following happen. Let's say I have 3 Testcases with the following results in RIDE:
Testcase Easter -- PASS
Testcase Christmas -- FAIL
Testcase Foo -- PASS
I want to take a screenshot which should be named testcase_christmas.png (or with ' ' instead of '_', that does not matter). Is there a possibility to do it dynamically, something like
${testcase}= Get Testcase Name
Capture Page Screenshot ${testcase}
or anything like that? I am using:
Python 2.7.x (latest) 32 bit
wxPython 2.8 32 bit
geckodriver latest 64 bit

Answer 1

Robot framework automatically sets the variable ${TEST NAME} to contain the name of the currently executing test. See Automatic Variables in the user guide)
The documentation for SeleniumLibrary's Capture Page Screenshot shows that you can give it a filename as the first argument.
Putting those two together, you can do this:
Capture page screenshot ${TEST NAME}.png

Answer 2

The way I would go about this is creating a test teardown and using automatic variables form robot framework. Found here: http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#automatic-variables
Your keywords page / resource file should have a load test data keyword that gets the test name, along with setting a test variable you can assign the screenshot too.
*** Keywords ***
Load Test Data
${data} Get File ${TEST NAME}.txt
Set Test Variable ${data} ${data}
Common Test Teardown
capture page screenshot ${data}.png
Your test should call whatever test teardown you decide to use.
*** Settings ***
Test Setup Load Test Data
*** Testcases ***
Test Case A
My keywords
[Teardown] Common Test Teardown
Calling the test setup allows you to load the name of each test in your file and in the teardown if it fails will take a screenshot with the test case name you loaded in your test setup.

If you want to save the screenshots on basis of test case ie. a separate folder for all screenshots related to each test case. Then you can use:
Set Screenshot Directory ./Screenshots/${SUITE NAME}/${TEST NAME}
Capture Page Screenshot ABC.png
A Screenshot directory will be created in the project root folder where all the screenshots will be stored in different folders based on the test case and test suites.
For a single suite you can use
Set Screenshot Directory ./Screenshots/${TEST NAME}
