Using Get Time in Robot Framework Test cases - robotframework

How to Use a particular Time For all the test cases in RF.Suppose i have to give time in some field of UI(User Interface).
I have to give that as current time plus 15 mins across all the test cases..How can this be done?
I have declared global variable in Resources.txt and this is being imported across all the test case files
${hr}= Get Time hour NOW + 15min
${min}= Get Time min NOW + 15min
When i run the test case, am getting the following error :
Setting variable '${hr}' failed: Creating a scalar variable with a list value in the Variable table is no longer possible. Create a list variable '#{hr}' and use it as a scalar variable '${hr}' instead.
Setting variable '${min}' failed: Creating a scalar variable with a list value in the Variable table is no longer possible. Create a list variable '#{min}' and use it as a scalar variable '${min}' instead.
But when i use the same in Test1.txt they are working fine..

If the code you are using is in the *** Variables *** section, the format is wrong. Within the variables table you cannot call keywords. What you're doing is creating a list named ${hr} with the literal value of ["Get Time", "hour", "NOW + 15min"]
From the robot framework user's guide:
The most common source for variables are Variable tables in test case
files and resource files. Variable tables are convenient, because they
allow creating variables in the same place as the rest of the test
data, and the needed syntax is very simple. Their main disadvantages
are that values are always strings and they cannot be created
dynamically.
You will need to call the Get Time keyword from within a keyword or test case. Since you want to do this at startup, you can call the keyword in the suite setup.
*** Keywords ***
initialize timestamp variables
${hr}= Get Time hour NOW + 15min
${min}= Get Time min NOW + 15min
set suite variable ${hr}
set suite variable ${min}
*** Settings ***
Suite setup initialize timestamp varaibles
If you do this in multiple suites, it's entirely possible that not all suites will use exactly the same value. An alternative solution would be to set a global variable, and only set it once. Each suite could detect if it's been set yet, and only set it if it hasn't been set.
You could also do this through a python based variable file.
Note: this solution only sets the variable for the current suite. If you do this in a suite initialization file (eg: mysuite/__init__.robot), you will need to use Set Global Variable rather than Set Suite Variable.

Robotframework, How to define a dynamic variable name

I want to Define variable having dynamic name.
For example
${${FILE}{VAR}} Create List // ${FILE} = TEST, ${VAR} = VAR
Then I want to get variable named '${TESTVAR}'.
Here is my Summarized code...
*** Settings ***
Library SeleniumLibrary
Library ExcelLibrary
Library Collections
*** Variables ***
${VAR}= VAR
*** Keywords ***
Open Document And Assign Variable
[Arguments] ${FILE}
Open Excel Document filename=${FILE} doc_id=doc_var
${${FILE}${VAR}} Create List # It doesn't work ..
The previous answer is not really accurate.
This can be achieved exactly with robot's "Variables inside variables" feature like so:
FOR ${idx} IN RANGE 3
${var_name} = Catenate SEPARATOR=_ var ${idx}
Set Suite Variable ${${var_name}} ${idx}
END
you get:
   var_1=1
   var_2=2
   var_3=3
Please note that variables resolution is happening only for keywords arguments (at least for robot version 3.1.2 that I am using), therefore either one of 'Set test variable', 'Set Suite Variable' or 'Set Global Variable' keywords must be used. The following won't work:
FOR ${idx} IN RANGE 3
${var_name} = Catenate SEPARATOR=_ var ${idx}
${${var_name}} = ${idx}
END
results in:
    No keyword with name '${${var_name}} =' found.
For your list case you just need to create a list variable and reassign it to dynamically named variable using the above mentioned keywords
This is currently not possible with Robot Framework. You can use "variables inside variables" to resolve the values of variables (see the documentation on this topic) but not to resolve/set the name of the variable itself.
Though I am afraid that would be confusing anyway. Maybe you can explain your motivations and people can come up with another solution for your problem.

Is it possible to give arguments inside variables in robot framework?

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.

How to use "get library instance" with global variable in robot framework

I have to define two variables ${p1} and ${p2} whose scope should be global means they can be use in various teat cases in a single test suite.
when I am doing the below activity inside test case it is working fine:
${p1}= GET LIBRARY INSTANCE P1
${p2}= GET LIBRARY INSTANCE P2
But when I am assigning p1 and p2 as global, I am not able to get the desired result:
set Suite Variable ${p1}= GET LIBRARY INSTANCE P1
set Suite Variable ${p2}= GET LIBRARY INSTANCE P2
I did not want to write ${p1}= GET LIBRARY INSTANCE P1 line in all test cases, what should I do? Any help will be appreciated.
You should define a Suite Setup in which you could set your variables for the whole suite. You should get your library instances first and then simply set those variables as suite variables like it is shown in the example.
${ID} = Get ID
Set Suite Variable ${ID}
In your case it should look like something this:
*** Settings ***
Suite Setup Setup Global Variables
*** Keywords ***
Setup Global Variables
${p1}= GET LIBRARY INSTANCE P1
${p2}= GET LIBRARY INSTANCE P2
Set Suite Variable ${p1}
Set Suite Variable ${p2}
*** Test Cases ***
Test CaseA
Log ${p1}
Log ${p2}
Test CaseB
Log ${p1}
Log ${p2}
Note that these variables will be accessible only in this suite file.
You are using invalid syntax. The documentation for Set suite variable says that it takes a variable name as the first argument and one or more values (not a keyword) as subsequent arguments. You are giving the string ${p1}= GET LIBRARY INSTANCE as the variable name, and the string P1 as the value.
The correct form is like the following. Because ${p1} exists locally you do not need to specify it when calling set suite variable.
${p1}= GET LIBRARY INSTANCE P1
set Suite Variable ${p1}

Robot: assign variables in setup phase using Run Keywords

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.

Using Variables in Variable definition

I am trying to get variables into variables but it wont work. I searched google and tried a lot of stuff but it did not wor out.
I hope this question ist not "dumb":
What am I doing wrong ?
*** Settings ***
Library SeleniumLibrary
Library OperatingSystem
*** Variable ***
${year} Get Time return year
${month} Get Time return month
${day} Get Time return day
${output} ${CURDIR}\Testing\Tests\SRV\csdb_#{year}-#{month}-#{day}.log
*** Testcases ***
Textfile should have a line saying the service is started
${errors} = Grep File ${output} Test
From the robot framework user's guide:
The most common source for variables are Variable tables in test case
files and resource files. Variable tables are convenient, because they
allow creating variables in the same place as the rest of the test
data, and the needed syntax is very simple. Their main disadvantages
are that values are always strings and they cannot be created
dynamically.
In order to do what you want, you'll need to define the variables in a keyword. For example:
*** Keywords ***
Get Output
${year}= Get Time year
${month}= Get Time month
${day}= Get Time day
${output}= Set variable ${CURDIR}/Testing/Tests/SRV/csdb_${year}-${month}-${day}.log
[Return] ${output}
*** Testcases ***
Textfile should have a line saying the service is started
${output}= Get Output
${errors} = Grep File ${output} Test
Note: you can fetch all three parts of the data in a single call to the keyword, like so:
${year} ${month} ${day}= Get Time year month day
It's a bit hard to read with the space-separated format, but the variable names must each be separated by two or more spaces, but "year month day" should have only one.
