I am using the robotframework for automating testing in one of my project.
I am trying to Set the variable based on the IF condition under *** variables*** section but i see that the whole if condition is getting assigned to it
For example, in one of robot file test.robot
*** Variables ***
${Host} = Set Variable If ${account} == test testingHost prodHost
I am passing the ${account} value from the command line as
robot --variable {account}:test
When i try to log the value of ${Host} what i see is the full if condition into it as output. Something like this
Started Noisy Test Case ... Set Variable If test==test testingHost
Followed the link of builtin(https://robotframework.org/robotframework/latest/libraries/BuiltIn.html#Set%20Variable%20If) library

I'm playing around with command-line arguments and had something working both with / without giving a command-line argument, but suddenly it starts failing if I don't give a command-line argument.
On https://groups.google.com/g/robotframework-users/c/_5Usp-K4Dlw?pli=1 I read that adding a space before the variable and comparing it to a value like this '${ VAR}'==<value> should work to check if a variable is existing or not.
The code-snippet that was working before is:
*** Test Cases ***
My test
[Documentation] test to check if the SUT reacts as expected
${is_test}= Evaluate '${ VAR}'=='test'
Log To Console ${is_test}
Run Keyword If ${is_test} Log To Console VAR == test
After changing the code to (Removed '[Documentation]' since it was copied from another test):
*** Test Cases ***
My test
${is_test}= Evaluate '${ VAR}'=='test'
Log To Console ${is_test}
Run Keyword If ${is_test}
... Log To Console VAR == test
it suddenly started failing with: Variable '${ VAR}' not found. errors.
And after changing it back to the original it still fails.
I can't figure what I did wrong in the change.
Note: The company I'm working for uses RobotFramework version 3.0.4 (yes I know ancient)
Managed to solve it by adding ${VAR} with some default value to a *** Variables *** list. But still I don't understand why it was originally working without that list.
Here is how your test should look like if you want to check if variable is empty and do something based on that.
*** Variables ***
${VAR}= test
*** Test Cases ***
My test
Run Keyword If '${VAR}'=='${EMPTY}' Log To Console Variable is empty
... ELSE Log To Console Variable is not empty
If you want variable default value to be empty and execute some keyword only if it comes from command line set variable as empty, for example:
*** Variables ***
${VAR}= ${EMPTY}
*** Test Cases ***
My test
Run Keyword If '${VAR}'=='${EMPTY}' Log To Console Variable is not set
... ELSE Log To Console Variable is ${VAR}
Run your test from command-line without passing variable
$ robot sample.robot
==============================================================================
Sample
==============================================================================
My test Variable is not set
My test | PASS |
------------------------------------------------------------------------------
Sample | PASS |
1 test, 1 passed, 0 failed
==============================================================================
Now, run with passing variable
$ robot -v VAR:test sample.robot
==============================================================================
Sample
==============================================================================
My test Variable is test
My test | PASS |
------------------------------------------------------------------------------
Sample | PASS |
1 test, 1 passed, 0 failed
==============================================================================
P.S. About space inside variable, I think it's just typo in Google Groups. If it was working then variable might be globally accessible or defined somewhere else.
Test 1.robot
*** Variables ***
${node} babitha
*** Test Cases ***
A Test Case
Log To Console ${node}
Test 2.robot
*** Settings ***
Resource C:\Users\2013\Desktop\Test 1.robot
*** Test Cases ***
A Test Case
Log To Console ${node}
Trying to print babitha on console when i am running Test 2.robot file
A resource file cannot contain *** Test Cases *** section - if you try to run your sample the framework will probably produce an error with such message.
If you want to use a variable from one suite in another, then in the initial one you declare it it as such with the Set Global Variable keyword:
Set Global Variable ${node} # you can reassign its value here, or leave to the previously set
This has one caveat though - you must be sure the setter is going to be called before the case that will try to use it (naturally) - otherwise, it will not be defined for it.
An alternative is to store the variable in a 3rd file (a resource one) and import it in the suites that need it.
And another alternative is to pass it with --variable node:babitha in the command line when running the tests - thus it will be globally available from the start, and all cases will be able to access it (and modify, through the Set Global Variable).
If more .robot files have to share some variable(s), it's better to keep these variables in a separate file (and folder), I'd suggest similar structure:
.
|__Resources
|__Tests
In Resources/, you will have a file I'll call config.py:
node = "babitha"
The last step you need is to load the config file in both of your test suites:
Tests/Test 1.robot
*** Settings ***
Variables ../Resources/config.py
*** Test Cases ***
A Test Case
Log To Console ${node}
Tests/Test 2.robot
*** Settings ***
Variables ../Resources/config.py
*** Test Cases ***
A Test Case
Log To Console ${node}
One remark at the end:
You used an absolute path C:\Users\2013\Desktop\Test 1.robot, try to avoid that, if someone else clones your project, it will likely break on their environment
Library REST ${base_url}
*** Keywords ***
Get Requests
GET ${rest_of_the_url}
Output response body
*** Test Cases ***
Do some searching
Get Requests
*** Variables ***
${base_url} https://business.com
${rest_of_the_url} /api/${department}/${person_name}
How can I assign values to ${department} and ${person_name}? I don't want to set those inside Variables because then I cannot write multiple scenarios inside one .robot file. Is it possible to do the assignment as arguments?
i do not think there is a way to pass arguments within the variables,
The below section is straight from the documentation of Robotframework,
where you can create Variables inside variables
Variables inside variables
Variables are allowed also inside variables, and when this syntax is used, variables are resolved from the inside out. For example, if you have a variable ${var${x}}, then ${x} is resolved first. If it has the value name, the final value is then the value of the variable ${varname}. There can be several nested variables, but resolving the outermost fails, if any of them does not exist.
In the example below, Do X gets the value ${JOHN HOME} or ${JANE HOME}, depending on if Get Name returns john or jane. If it returns something else, resolving ${${name} HOME} fails.
*** Variables ***
${JOHN HOME} /home/john
${JANE HOME} /home/jane
*** Test Cases ***
Example
${name} = Get Name
Do X ${${name} HOME}
E.g.,
${person_name}= Set Variable Matt
${department}= Set Variable R&D
# then your code continues
${rest_of_the_url} /api/${department}/${person_name}
Set Variable documentation.
Try to see this using the Set Test / Suite / Global Variable keywords here:
https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html
Use "Set Suite Variable" keyword then enter the variables $ {person_name} e
$ {department} inside * Variables * then you should read the value inside the test.
I'm trying to create a setup phase for a test case in which I assign variables. I know in order to do multiple keywords I need to use Run Keywords, but is it possible to set variables when doing this? For example:
*** Test Cases ***
Case1
[Setup] Run Keywords
... ${var1}= Keyword1
... AND ${var2}= Keyword2
obviously the above doesn't work because ${var1} and ${var2} are just treated as arguments to Run Keywords. Since they haven't been defined yet, setup fails.
No, you cannot. Even though you added "using Run Keywords", this question has the same answer as Is possible to create new variable in suite/test set up - Robot Framework?
You can use the Set Suite Variable keywork to do that.
set suite variable ${var1} Hello World
You might need to escape the variable...
set suite variable \${var1} Hello World
From the builtin library documentation:
If a variable already exists within the new scope, its value will be overwritten. Otherwise a new variable is created. If a variable already exists within the current scope, the value can be left empty and the variable within the new scope gets the value within the current scope.
The question here why are you trying to do this?
The way I do it, if I want to call keywords and set their outputs in variables
to reuse them in my test suite, I do the following:
*** Settings ***
Library BuiltIn
Suite Setup Initialize Variables
*** Keywords ***
Initialize Variables
${Argument1} = Set Variable some_value
${output1} = Keyword1 ${Argument1}
${output2} = Keyword2
${output3} = Keyword3 ${Argument1} other_value
*** Test Cases ***
Test Case 1
# Here you can use the variables that you initialized in the Suite Setup.
Log ${output1}
Log ${output2}
Log ${output3}
Test Case 2
# Also here you can use the same variables.
No Operation
Note: If you want to setup the variables for each test case, you can do it either in the settings section like this:
*** Settings ***
Test Setup Initialize Variables
Or you can use the setting in the test case itself (same as what you did in your question)
Test Case 1
[Setup] Initialize Variables
Note that "Initialize Variables" can take arguments as well if you need.
From what I read about variable scopes and importing resource files in robotframework doc i would expect this to work (python 2.7, RF 2.8.7):
Test file:
*** Settings ***
Resource VarRes.txt
Suite Setup Preconditions
*** Variables ***
*** Test Cases ***
VarDemo
Log To Console imported [${TODAY}]
*** Keywords ***
Resource file:
*** Settings ***
Library DateTime
*** Variables ***
${TODAY} ${EMPTY} # Initialised during setup, see keyword Preconditions
*** Keywords ***
Format Local Date
[Arguments] ${inc} ${format}
${date} = Get Current Date time_zone=local increment=${inc} day result_format=${format}
[Return] ${date} # formatted date
Preconditions
${TODAY} = Format Local Date 0 %Y-%m-%d
Log To Console inited [${TODAY}]
However the output is:
inited [2015-03-20]
imported []
RF documentation states:
Variables with the test suite scope are available anywhere in the test
suite where they are defined or imported. They can be created in
Variable tables, imported from resource and ....
which I think is done here.
If I add a line to keyword Preconditions like this, it works:
Preconditions
${TODAY} = Format Local Date 0 %Y-%m-%d
Set Suite Variable ${TODAY}
Log To Console inited [${TODAY}]
The reason is that in the first line a local variable is defined, instead of initialising the test suite variable declared in the variable table. A paragraph in RF doc hints to that:
Variables set during the test execution either using return values
from keywords or using Set Test/Suite/Global Variable keywords always
override possible existing variables in the scope where they are set
I think a major drawback of RF is that you cannot define variables dynamically in the variable table. Setting the scope of a variable from within a keyword is something I try to avoid.
For dynamic variables, you might to use a variable file in Python. See the section "Implementing variable file as Python or Java class" in the User Guide.
For example, I use a variables.py with:
if platform.system() in ['Darwin', 'Linux']:
OS_FAMILY = 'unix'
elif platform.system() == 'Windows':
OS_FAMILY = 'windows'
else:
OS_FAMILY = 'unknown'
OS_FAMILY_IS_UNIX = OS_FAMILY == 'unix'
OS_FAMILY_IS_WINDOWS = OS_FAMILY == 'windows'
Then in the Robot Tests I can use the dynamic variables ${OS_FAMILY}, ${OS_FAMILY_IS_UNIX}, and ${OS_FAMILY_IS_WINDOWS} anywhere.
You should be able to do create your ${TODAY} variable.
