In Robot Automation, how to re-run the failed test case immediately if it is failed, before going to another test case execution.
For instance,
*** Test Cases ***
Login User And Create Another User
Login User ....
Create Another User ...
Login With New User
Login User..
Test Function ABC
.....
.....
Since one test has a dependency on another test, I need to re-run the failed case immediately after it is failed. Before executing another test.
In one word, you can't, and you shouldn't; a case is a case, with binary outcome. And if you have dependencies between tests, that's a smelly design; try to change it to a pre-condition (env setup) for the second case, so it is atomic.
Disclaimer: this rant is for the automatic re-execution in a single run. After a run has finished, RF has baked-in functionality to re-execute just the failed ones (so flaky tests are given the chance to succeed); but as I understood your question, you are not asking for the latter.
In two words, if you really need to do it, you can; extract the whole test case in a keyword, and call it inside Wait Until Keyword Succeeds, giving it 2 (or more?) attempts:
*** Test Cases ***
Test Function ABC
Wait Until Keyword Succeeds 2 times 100ms The Actual Test For Function ABC
*** Keywords ***
The Actual Test For Function ABC

I'm running a LoadRunner test , upon user failure at login /even at any other transaction it has to fail and execute log off portion of the script.
Note: I have put text check and with textcheck count if the transaction fails( using if condition I have handled it) it then ends transaction with fail status .I would need solution to perform log off also at the point where the if condition fails.
Can anyone share me with an example to execute log off when textcheck fails.
Depends upon your language choice.
Assuming you have the default language of C with your HTTP virtual user, then simply implement a logout function which contains your logout code. Call that function upon failure of your condition. A "return 1;" inside of that if/then conditional will also start a new iteration immediately. "return 0;" goes to a new iteration with respected pacing. "return -1;" kills the virtual user altogether.
Scenario:
There are 5 Links in the Home page:
Link 1
Link 2
Link 3
Link 4
Link 5
Each of the above links are separate test cases, so there are a total of 5 test cases.
All the links may not present in all the sites, according to the requirements.
So I need to write a Robot framework test case which works dynamically for all the sites, Like 1 site may have 3 links only some has all the 5 links. So its like SKIPPING a particular Test case if that lisk is not present.

Can anyone help.
In the upcoming Robot Framework Release 4.0 a new test status skipped will be introduced. Here is a brief status about the release:
Past due by 27 days 87% complete
Major release concentrating on adding the skip status (#3622), IF/ELSE
(#3074) and enhancing the listener API (#3296 and #3538). Last major
release to support Python 2.
So it can be ready any time soon now.
This is what you can have New SKIP status #3622. There will be a Skip If and a Skip keywords and more to be used.
How to skip tests
There are going to be multiple ways:
A special exception that library keywords can use to mark a single test to be skipped. See also #3685.
BuiltIn keyword Skip (or Skip Test and Skip Task) that utilizes the aforementioned exception.
BuiltIn keyowrd Skip If to skip based on condition.
When the skipping exception is used in a suite setup, all tests in the suite are skipped.
Command line option --skip to unconditionally skip tests based on tags. Similar to --exclude but skipped tests are shown in logs/reports
with a skip status and not dropped from execution altogether.
Command line option --skiponfailure to skip tests if they fail. Similar effect than with the current --noncritical.
What about criticality
As already discussed in #2087, the skip status is very similar feature
than Robot's current criticality concept. There are many people who
would like to have both, but I don't think that's a good idea and
believe it's better to remove criticality when skipping is added.
Separate issue #3624 covers removing criticality and explains this in
more detail. Colors
Skip status needs a specific color to match current pass (green) and
fail (red). Yellow feels like a good candidate with a traffic light
metaphor, but I'm open for other ideas and we could possibly change
other colors as well. Probably should make colors configurable too --
currently only report background colors support it.
Report background color mentioned above needs some thinking as well.
Currently it's either green or red, but with the added skip status we
could use also yellow or whatever skip color we decide to use.
Different scenarios where different colors could be used are listed
below (assuming green/yellow/red scheme):
All tests pass. This is naturally green.
Any test fails. This is naturally red.
Any test is skipped (no failures). This probably should be green but could also be yellow.
All tests skipped. This could be yellow. Could also be green but that's a bit odd if all tests are yellow.
Depending on your deadlines you might won't be able to wait this release, nevertheless it is a good to know thing.
There is an advanced solution where you can generate your test cases run-time. To do so you have to implement a small library that also acts as a listener. This way it can have a start_suite method that will be invoked and it will get the suite(s) as Python object(s), robot.running.model.TestSuite. Then you could use this object along with Robot Framework's API to create new test cases. The idea below was inspired by and it is based on this blog post: Dynamically create test cases with Robot Framework.
DynamicTestLibrary.py:
from robot.running.model import TestSuite
class DynamicTestLibrary(object):
ROBOT_LISTENER_API_VERSION = 3
ROBOT_LIBRARY_SCOPE = 'GLOBAL'
ROBOT_LIBRARY_VERSION = 0.1
def __init__(self):
self.ROBOT_LIBRARY_LISTENER = self
self.top_suite = None
def _start_suite(self, suite, result):
self.top_suite = suite
self.top_suite.tests.clear() # remove placeholder test
def add_test_case(self, keyword, *args):
tc = self.top_suite.tests.create(name=keyword)
tc.keywords.create(name=keyword, args=args)
globals()[__name__] = DynamicTestLibrary
UPDATE for Robot Framework 4.0
Due to the backward incompatible changes (Running and result models have been changed) made in the 4.0 release the add_test_case function should be change as below if you are using version above 4.0.
def add_test_case(self, name, keyword, *args):
tc = self.top_suite.tests.create(name=name)
tc.body.create_keyword(name=keyword, args=args)
You can utilize this library in a suite setup, in which you check which links are present and add test cases for the ones that are available.

Is it possible to handle exceptions from the test case? I have 2 kinds of failure I want to track: a test failed to run, and a test ran but received the wrong output. If I need to raise an exception to fail my test, how can I distinguish between the two failure types? So say I have the following:
*** Test Cases ***
Case 1
Login 1.2.3.4 user pass
Check Log For this log line
If I can't log in, then the Login Keyword would raise an ExecutionError. If the log file doesn't exist, I would also get an ExecutionError. But if the log file does exist and the line isn't in the log, I should get an OutputError.
I may want to immediately fail the test on an ExecutionError, since it means my test did not run and there is some issue that needs to be fixed in the environment or with the test case. But on an OutputError, I may want to continue the test. It may only refer to a single piece of output and the test may be valuable to continue to check the rest of the output.
How can this be done?
Robot has several keywords for dealing with errors, such as Run keyword and ignore error which can be used to run another keyword that might fail. From the documentation:
This keyword returns two values, so that the first is either string
PASS or FAIL, depending on the status of the executed keyword. The
second value is either the return value of the keyword or the received
error message. See Run Keyword And Return Status If you are only
interested in the execution status.
That being said, it might be easier to write a python-based keyword which calls your Login keyword, since it will be easier to deal with multiple exceptions.
You can use something like this
${err_msg}= Run Keyword And Expect Error * <Your keyword>
Should Not Be Empty ${err_msg}
There are couple of different variations you could try like
Run Keyword And Continue On Failure, Run Keyword And Expect Error, Run Keyword And Ignore Error for the first statement above.
Option for the second statement above are Should Be Equal As Strings, Should Contain, Should Match.

How does one use the flag options for benchmarks with the gocheck testing framework? In the link that I provided it seems to be that the only example they provide is by running go test -check.b, however, they do not provide additional comments on how it works so its hard to use it. I could not even find the -check in the go documentation when I did go help test nor when I did go help testflag. In particular I want to know how to use the benchmark testing framework better and control how long it runs for or for how many iterations it runs for etc etc. For example in the example they provide:
func (s *MySuite) BenchmarkLogic(c *C) {
for i := 0; i < c.N; i++ {
// Logic to benchmark
}
}
There is the variable c.N. How does one specify that variable? Is it through the actual program itself or is it through go test and its flags or the command line?
On the side note, the documentation from go help testflag did talk about -bench regex, benchmem and benchtime t options, however, it does not talk about the -check.b option. However I did try to run these options as described there but it didn't really do anything I could notice. Does gocheck work with the original options for go test?
The main problem I see is that there is no clear documentation for how to use the gocheck tool or its commands. I accidentally gave it a wrong flag and it threw me a error message suggesting useful commands that I need (which limited description):
-check.b=false: Run benchmarks
-check.btime=1s: approximate run time for each benchmark
-check.f="": Regular expression selecting which tests and/or suites to run
-check.list=false: List the names of all tests that will be run
-check.v=false: Verbose mode
-check.vv=false: Super verbose mode (disables output caching)
-check.work=false: Display and do not remove the test working directory
-gocheck.b=false: Run benchmarks
-gocheck.btime=1s: approximate run time for each benchmark
-gocheck.f="": Regular expression selecting which tests and/or suites to run
-gocheck.list=false: List the names of all tests that will be run
-gocheck.v=false: Verbose mode

-test.blockprofilerate=1: if >= 0, calls runtime.SetBlockProfileRate()
-test.coverprofile="": write a coverage profile to the named file after execution
-test.cpu="": comma-separated list of number of CPUs to use for each test
-test.cpuprofile="": write a cpu profile to the named file during execution
-test.memprofile="": write a memory profile to the named file after execution
-test.memprofilerate=0: if >=0, sets runtime.MemProfileRate
-test.outputdir="": directory in which to write profiles
-test.parallel=1: maximum test parallelism
-test.run="": regular expression to select tests and examples to run
-test.short=false: run smaller test suite to save time
-test.timeout=0: if positive, sets an aggregate time limit for all tests
-test.v=false: verbose: print additional output
is writing wrong commands the only way to get some help with this tool? it doesn't have a help flag or something?
I'm 5 years late, but to specify how many N times to run. Use the option -benchtime Nx.
Example:
go test -bench=. -benchtime 100x
BenchmarkTest 100 ... ns/op
Please read more about all go testing flags here.
see the Description_of_testing_flags:
-bench regexp
Run benchmarks matching the regular expression.
By default, no benchmarks run. To run all benchmarks,
use '-bench .' or '-bench=.'.
-check.b works the same way as -test.bench.
E.g. to run all benchmarks:
go test -check.b=.
to run a specific benchmark:
go test -check.b=BenchmarkLogic

I need to call two teardown keywords in test case but must not create new keyword for that.
I am interesting if there is a such syntax for keywords as for documentation or loops for example:
[Documentation] line1
... line2
... line3
Use the "Run Keywords" keyword.
From doc "This keyword is mainly useful in setups and teardowns when they need to take care of multiple actions and creating a new higher level user keyword would be an overkill"
Would look like that:
Test Case
[Teardown] Run Keywords Teardown 1 Teardown 2
or also
Test Case
[Teardown] Run Keywords Teardown 1
... Teardown 2
and with arguments
Test Case
[Teardown] Run Keywords Teardown 1 arg1 arg2
... AND Teardown 2 arg1
For executing multiple keywords in Test Teardown method use the following trick:
Firstly, define a new keyword containing the set of keywords you want to execute.
E.g. here Failed Case Handle is a new definition of the other two keywords take screenshot and close application. Consider this is to take a screenshot and then close the running application.
*** Keywords ***
Failed Case Handle
take screenshot
close application
Basically, when you call the Failed Case Handle keyword, take screenshot and close application will be executed respectively.
Then, in the ***Settings*** section define the Test Teardown procedure by the following example.
*** Settings ***
Test Teardown run keyword if test failed Failed Case Handle
or,
*** Settings ***
Test Teardown run keyword Failed Case Handle
So, in the first case Failed Case Handle keyword will be called if any test case fails. On the other-hand in the second case Failed Case Handle keyword will be called after each test cases.
