Handling System hang in Robot framework - robotframework

I am facing a problem regarding implementation for Robot testcases for System Hang.
*** Settings ***
Library SSHLibrary
*** Test Cases ***
Process Crash Dump
Wait Until Keyword Succeeds 50sec 10sec Execute Command echo c > /proc/sysrq-trigger
Should Be Equal 1 1
Here while "Execute Command echo c > /proc/sysrq-trigger" the testcase is getting stucked up and not proceeding furthur. Is there any kind of mechanism to come out after giving the command and later i'll check for system to start.

The problem is resolved, by using
Start Command echo c > /proc/sysrq-trigger
Which issues command and exits. Then I am doing my stuff to check System is active or not.

You can set a timeout on a testcase with the [Timeout] setting in a testcase, or Test Timeout in the suite settings. See Test case time out in the robot framework users guide. From the documentation:
If there is a timeout, the keyword running is stopped at the
expiration of the timeout and the test case fails. However, keywords
executed as test teardown are not interrupted if a test timeout
occurs, because they are normally engaged in important clean-up
activities. If necessary, it is possible to interrupt also these
keywords with user keyword timeouts.

robot framework stop teardown execution in failure

I'm using robot framework to test my application
I use teardown in my test.
It works as expected, if my test ends or fails, teardown starts the execution. My problem starts when the teardown execution fails, then I want it to stop.
*** Test Cases ***
Test new data import
Setup test case
Run test case
[Teardown] TearDown test case
Teardown test case
Insert name in filter
Delete user
The scenarios is when "Insert name in filter" fails, I want it to stop running, but it executes the "Delete user" keyword.
Is it possible to prevent?
I finally do some research and see why the use of --exitonfailure (suggested in other answer) didn't work for me,it's because it misses the teardown workflow.
https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#id689 that teardown execution can be stopped
Teardown -> Also they are executed fully even if some of their keywords fail.
So, what I did to solve was use Run Keyword and return Status and Run Keyword if to solve:
*** Test Cases ***
Test new data import
Setup test case
Run test case
[Teardown] TearDown test case
Teardown test case
${filterStatus} Run keyword and return status Insert name in filter
Run keyword if ${filterStatus} Delete user
... ELSE fail Filter filter by name failed
Try this to prevent to executing "Delete user" keyword when calling exitonfailure: http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#stopping-when-first-test-case-fails
Usage: When options are used, they must always be given between the runner script and the data sources
--exitonfailure -x
Example: robot --exitonfailure 01_robot_test.robot
If option --exitonfailure (-X) is used, test execution stops immediately if any critical test fails. The remaining tests are marked as failed without actually executing them.

Log and Report button is getting disabled in RIDE after executing test case

i am running the test on VM client machine, sometimes when i run the tests it's got executed properly but the Log and Report buttons are getting disabled and i am able to find the Log path to open the log. But sometimes the Test won't stop even after completing the steps execution, the elapsed time is still running and when click Stop for 2 to 3 times the execution will stop and i didn't get any reports or logs for that test.
I have encountered the same error while running Selenium tests. When this happens, open your task manager and check out your background processes. You might see there are multiple chromedriver.exe/geckodriver.exe processes running. This happens when you have not terminated your test case gracefully (in my case, not closing the browser) which leads to disabling of both Log and Report button. To fix this you will be needing to use
Browser Close
keyword at the end of your test case. In short, graceful termination was missing in your test case.
*** Settings ***
Library Selenium2Library
*** Test Cases ***
sample_test
# ->Perform Functionality<-
# Graceful Termination
s2l.Browser Close
This will kill the background webdriver processes. Now on the log and report button will be in enabled state each time you run the test.
Check out this response: Log and Report buttons are disabled in RIDE

Robotframework: behavior when teardown fails

I'm trying to understand how Robot behaves when there is a failure in Test teardown.
Conceptually, I would think that if a test case completes execution, it should be considered passed. Teardown is not part of the test, so if there is a failure in teardown, the test case should still be marked as passed. The behavior I observe is that if test teardown fails, the test case fails. Is this what is supposed to happen, and is there any way to change it?
I'm also seeing something weird when Suite teardown fails.
The console output shows the test case as passed, displaying |PASS| next to the case. However, the statistics at the bottom of the output show all cases as failed.
Here's an example:
*** Settings ***
Suite Teardown Teardown
*** Keywords ***
Setup
Log to Console setup
Teardown
Should Be Equal 1 2
*** Test Cases ***
case1
[Setup] Setup
Log To Console case
and the output:
==============================================================================
Test
==============================================================================
case1 setup
.case
case1 | PASS |
------------------------------------------------------------------------------
Test | FAIL |
Suite teardown failed:
1 != 2
1 critical test, 0 passed, 1 failed
1 test total, 0 passed, 1 failed
==============================================================================
This is just confusing. The test passes, and is shown as passed, but is marked as failed in the stats. Is this a bug, or is there some way to fix it?
Sometimes the test fails in tear down is an important issue, for example, the clean up is not completed and it causes other test cases to fail. Therefore robot framework always reports FAIL if the test case fails in tear down. Use Run Keyword And Ignore Error if the keyword failure is not an issue to your test case:
*** Keywords ***
Teardown
Run Keyword And Ignore Error Should Be Equal 1 2
However you should be careful that if the keyword fails, nothing is reported unless you check the detail in output logs.
The suite tear down runs after all test cases finished. The first test case is passed and program prints PASS. After that, the suite tear down runs and it fails, so the program prints FAIL. This is expected result. It is easier to understand if there are more test cases in one suite, for example:
Test suite A
run case 1 ----> print PASS
run case 2 ----> print PASS
run case 3 ----> print PASS
run suite teardown ----> print FAIL (and change case 1, 2, 3 to FAIL)
And tear down fail is the same as test case fail in robot framework, therefore robot framework reports all test cases fail in the end. Check the output log.html, you can see that all test cases are FAIL.
I figured out a solution that may or may not be useful. We have a Jenkins integration and Jenkins will report all these test failures that I want to see as passed. What I did was not generate the html from robot, just the xml.
I then used etree to create a new test xml tag.
def create_test(id= 'sx-tx', name='Test'):
return ET.Element("test", attrib={'id': id, 'name': name})
I copied the teardown internals to the new test and used 'rebot' to generate the xml from the new xml. This made Teardown a test so it showed only a single failure.
I can elaborate if you would like.

Robot Framework : How to use test time out for test case

I have test suit which has multiple test cases and to avoid execution halt of test suite , I wants to add test time out for each test case . How to do this please help.
According to the robot framework user guide, you define the default timeout in the settings. This is the example from the user guide:
*** Settings ***
Test Timeout 2 minutes
You can specify a test case or keyword specific timeout with the [Timeout] setting:
*** Test Cases ***
Example
[Timeout] 1 minute
Alternatively you could use the built in Wait conditions
Wait For Element To Be Visible ${ELEMENT_LOCATOR} 30s
These have a second argument for timeout.

How to stop Robot Framework test execution if first testcase FAIL?

As shown in below robot file, I have three testcases. I want to stop the test execution, if TESTCASE1 fails. TESTCASE2 should be executed only if TESTCASE1 passes.
*** Settings ***
Library pythonLib
*** Test cases ***
TESTCASE1
boot device
TESTCASE2
configure device
TESTCASE3
restart device
Is there any keyword or custom way to do this ?
There is a command line option for this, if you want the behavior that robot should stop running as soon as any test fails. This option is --exitonfailure. From the robot framework user guide, in a section titled Stopping when the first test fails:
If option --exitonfailure is used, test execution stops immediately if
any critical test fails. Also the remaining tests are marked as
failed.
You might also want to take a look at this answer to the question Automatic failing/non-execution of interdependent tests in Robot Framework, which shows how to write a keyword to implement dependencies between test cases.
There are multiple ways to get the job done, each appropriate for different situations.
--exitonfailure
The command line option --exitonfailure aborts the test run after any testcase fails, unless it is marked noncritical.
Fatal Error
You might only want to abort if exactly TESTCASE1 fails. The Fatal Error keyword exist just for this purpose:
TESTCASE1
${passed}= Run Keyword And Return Status boot device
Run Keyword If not ${passed} Fatal Error
If this seems clunky to you, you can throw fatal errors directly from Python/Java.
Suite Setup
These tools will get the job done, and are appropriate in some cases. Although in the asker's case, I observe:
The first testcase must pass for any other tests to run.
It runs a keyword called boot device.
To me that is not a testcase. That is a setup. If you need a setup to run once before a suite of testcases, you should specify it as a Suite Setup.
***Settings***
Suite Setup boot device
--pause_on_failure, this will stop the execution, whenever script hit the error. Script execution won't be resumed unless you explicitly start.
