I'm trying to iterate a collection, it contains the ID of an HTML element. If I tried to compare the ID (i.e., Collection Item) with a hard coded string, it gives a RUN TIME ERROR. - Robot Framework and Selenium
Evaluating expression ''[u'Convert To String', u'DEFAULT']' !=
'DEFAULT' AND' failed: SyntaxError: invalid syntax (, line 1)
My Code is
*** Variables ***
#{HeaderCollection}= DEFAULT ONE TWO THREE
*** Test Cases ***
Click Items
:FOR ${item} IN #{HeaderCollection}
\ ${header} Set Variable Convert To String ${item}
\ Run Keyword If '${header}' != 'DEFAULT' click element ${header}
I tried the following code too
*** Test Cases ***
Click Items
:FOR ${header} IN #{HeaderCollection}
\ Run Keyword If '${header}' != 'DEFAULT' click element ${header}
Kindly assist me how to compare a item which is present in collection with a hard coded string value.
${header} Set Variable Convert To String ${item}
In the line above, you are attempting to run the keyword Set Variable by passing it another keyword Convert to String which is the incorrect usage.
Seeing as all the items #{HeaderCollection} are Strings to begin with, there is really no reason for this line to exist at all, but if it is absolutely required, it should be as follows:
${header} Set Variable ${item}

I have several Robot Framework keywords that return a basic string.
#keyword
def keyword_one():
return 'one'
#keyword
def keyword_two():
return 'two'
In a robot test case, I try to build a list with this items, but I can't figure out how to do that is one line.
*** Test Cases ***
Test Case List
#{my_list}= Create List Keyword One Keywork Two
I tried several syntax but can't make it work.
Of course, something like below works (hardcoded values).
*** Test Cases ***
Test Case List
#{my_list}= Create List one two
Thanks for your help.
At the time that I write this, robot doesn't have the ability to call keywords inline, so what you want isn't directly possible.
You could write your own keyword to do this, however. The keyword can accept multiple keywords as arguments, and use run keyword from the built-in library to run the keyword.
For example, the following keyword definition creates a keyword that creates a list of results from multiple keywords:
Keyword written in python
If you want to try this out, name the file example.py
from robot.libraries.BuiltIn import BuiltIn
builtin = BuiltIn()
def create_list_from_keywords(*keywords):
result = []
for keyword in keywords:
result.append(builtin.run_keyword(keyword))
return result
Example test
*** Settings ***
Library example.py
*** Keywords ***
Keyword one
return from keyword one
Keyword two
return from keyword two
*** Test cases ***
Example
#{actual}= create list from keywords Keyword one Keyword two
#{expected}= create list one two
Should be equal ${actual} ${expected}
Robot-based keyword definition
If you're uncomfortable with python, here's a robot-based keyword definition:
Create list from keywords
[Arguments] #{keywords}
[Return] #{result}
#{result}= create list
FOR ${keyword} IN #{keywords}
${keyword result}= Run keyword ${keyword}
Append to list ${result} ${keyword result}
END
At the moment you are adding the keywords to the list, not the values returned from running those keywords
You would need to call the keywords to get the returned values and add them to the list e.g.
*** Test Cases ***
Test Case List
${keyword_one_val} Keyword One
${keyword_two_val} Keyword Two
#{my_list}= Create List ${keyword_one_val} ${keyword_two_val}
log to console ${my_list}
which outputs:
['one', 'two']
I have several tests in robot. the Idea of all the tests is identical:
- load some parameter to module
- run
- compare expected to actual results
The only thing is different from test to test, is the input and the expected results.
I would like to run the test repeatedly but with different inputs- and each iteration will be considered as different test case - Instead of copy the same code for all of the test cases and change the inputs.
each iteration will have its own test case tag \ documentation \ name (lets say the iteration number)
for example:
FOR ${TC} IN #{TCS} #TCS is array of inputs and expected output
*** Test Cases ***
# edit the tag \ documentation \ test name
module.load ${TC['input']}
${output} = module.run
isValid ${output} ${TC['expectedOutput']}
END
Is it possible in robot?
Thanks:)
The easyest way is to define a Keyword with Arguments and Return Values.
You can call this Keyword in every Tescase (with specified tag/documentation etc), with specified Arguments for the Test and check the Reuturn Values.
You could use the test template feature of the framework, especially the template tests with for loop.
Using it would give the following advantages:
No code duplication. You need one keyword with the test logic, that will be invoked with all list elements.
Each iteration will be independent from the other. So if one iteration fails, the next will be still executed.
It is flexible. The number of iterations is dynamic, you can create an input list in a test or suite setup phase.
Example, note that I am providing my inputs from a variable file.
*** Settings ***
Variables VariableFile.py
*** Test Cases ***
Math test
[Template] Multiplication by 2
FOR ${TC} IN #{TCS}
input=${TC.input} output=${TC.output}
END
*** Keywords ***
Multiplication by 2
[arguments] ${input} ${output}
${result}= Evaluate ${input}*2
Should Be Equal As Integers ${output} ${result} Calculated result:${result} is not equal with the expected:${output}
Variable file:
class DataSet(object):
def __init__(self, input, output):
self.input = input
self.output = output
def __str__(self):
return f'i:{self.input} - o:{self.output}'
TCS = [DataSet(1,2), DataSet(2,4), DataSet(3,6), DataSet(3,7), DataSet(4,8)]
This is the output:
${rowcount}= Keyword1 Book1.xlsx 0
${length}= Set Variable ${rowcount}
${i} Set Variable 1
:FOR ${rowvalue} IN RANGE ${rowcount}
\ #{columnlist}= Keyword2 ${rowvalue}
Keyword2 is returning List of data. I want to check whether it is returning Empty List. Please help me with this?
The BuiltIn library has keywords Should be empty and Should not be empty which can be used to validate the length of a list.
Should Be Empty ${columnlist}
Should Not Be Empty ${columnlist}
Just in case someone else comes here looking for an answer which also addresses:
If ${columnlist} is not empty then I have to execute keyword below it. Is it possible using If statement? – Orsu Suni Jun 12 '17 at 4:44
Either one of these options should help (NOTE: only used within RIDE, I imagine they will work for others as well):
${len} Get Length ${columnlist} ---- will return zero if list is empty, you can then use ${len} in your conditional.
'#{columnlist}' == '#{EMPTY}' ---- should return true if list is empty, although so far I have only used it with RUN KEYWORD IF.
Alternatively you could run the following keyword:
${isEmpty} Run Keyword And Return Status Should Be Empty ${columnlist}
Then you get a boolean value in ${isEmpty} with whether the list is empty or not.
Statements/conditions in Robot are a bit confusing in my opinion. Previous suggestion 2. doesn't work for me. I'm using: Robot Framework 3.1.2 (Python 3.4.1 on win32)
I obtain expected solution:
*** Test Cases ***
TC1
${marker_files} Create List dummy3 dummy4 dummy5
Run keyword unless ${marker_files} == #{EMPTY} Operation on list
marker_files=${marker_files}
tc2
${marker_files} Create List #{EMPTY}
Run keyword unless ${marker_files} == #{EMPTY} Operation on list
marker_files=${marker_files}
*** Keywords ***
Operation on list
[Arguments] ${marker_files}=def
log to console \ndo something on list
first time posting here. I've a feeling that this is a really dumb question, but for some reason my code keeps failing and I just can't put my finger on what's wrong.
Here's is what I have:

Test Robot Framework Logging
#{ALLOWED}= Create List /page1 /page2 /page3
${ControllersList}= Get File ${EXEC_DIR}/Resources/controllers.txt
#{PAGES}= Split to lines ${ControllersList}
:FOR ${PAGE} IN #{PAGES}
\ Run Keyword If '${PAGE} IN #{ALLOWED}' Log Testing WARN
[Teardown] Close Browser
This is the output:
Evaluating expression ''/page1 IN [u'/page1', u'/page2', u'/page3']'' failed: SyntaxError: invalid syntax (<string>, line 1)
If I change the condition to something like this it works:
'${PAGE} == /page1'
I checked the documentation and it seems that the IN condition could be used. I'm totally lost here. Any hints? Thanks!
This is the proper way to do the expression:
Run Keyword If $PAGE in $ALLOWED Log Testing WARN
By removing the quotes and the curly braces, robot is able to treat PAGE and ALLOWED as python variables when evaluating the expression.
From the section Evaluating Expressions in the documentation for the BuiltIn library:
Starting from Robot Framework 2.9, variables themselves are automatically available in the evaluation namespace. They can be accessed using special variable syntax without the curly braces like $variable. These variables should never be quoted, and in fact they are not even replaced inside strings.
Also, when using keywords like Run Keyword If, the expression must be a valid python expression after variable substitution. Therefore, you must use the operator in rather than IN. The latter is used only by the robot :FOR statement.
Example
*** Variables ***
#{ALLOWED} /page1 /page2 /page3
*** Test Cases ***
Example that passes
${PAGE}= set variable /page1
Run Keyword If $PAGE in $ALLOWED
... pass execution ${PAGE} is allowed
fail ${PAGE} is not allowed
Example that fails
${PAGE}= set variable /page99
Run Keyword If $PAGE in $ALLOWED
... pass execution ${PAGE} is allowed
fail ${PAGE} is not allowed
The check was almost right, but you've effectively turned the Boolean expression into a String by surrounding it with the quotes. Here's the syntax that'll do it:
\ Run Keyword If $PAGE in $ALLOWED Log Testing WARN
Mind there are no curly brackets {} around the variable names - thus the check is (almost) the straight python's variable in another_variable
The documentation Evaluating Expressions does indeed specify that in construction used in the evaluation itself. An alternative approach is to use the Collections library keyword Get Match Count. This will return 0 when no results are found, and not generate a test failure.

\ ... ELSE IF ('${InList}' == '1') Log To Console 1 Page Found
\ ... ELSE Log To Console More pages found.
I have a scenario in which I would have to read from a dictionary and create variables with key as the variable name and value as the variable's value.
For example, if "hello": "world" is a dictionary item, then I have to set hello = world. This variable also needs to be later called in a test case. I tried to achieve this via below method but not sure if it has the right syntax and anyway it fails with No keyword with name '${$k}} found error.
Can anyone let me know if this can be done?

Spin Variables
${items}= get dictionary items ${arg}
:For ${k} ${v} IN #{items}
\ ${${k}}= set variable ${v}
