Programmatically create a Robot Framework test suite, then programmatically create a version we can save on disk

programmatic_rf.py

# Example from https://robot-framework.readthedocs.io/en/latest/autodoc/robot.running.html#examples
from robot.api import TestSuite

suite = TestSuite('Activate Skynet')
suite.resource.imports.library('OperatingSystem')
test = suite.tests.create('Should Activate Skynet')
test.keywords.create('Set Environment Variable', args=['SKYNET', 'activated'])
test.keywords.create('Environment Variable Should Be Set', args=['SKYNET'])

result = suite.run(output='skynet.xml')

# This is how you turn the suite created above to something we can write on disk

from robot.api import TestCaseFile

tc = TestCaseFile(source='foobar.robot')
settings_table = tc.start_table(['Settings'])
[settings_table.add_library(i.name) for i in suite.resource.imports]
testcases = tc.start_table(['Test Cases'])
for t in suite.tests:
    parsing_tc = testcases.add(t.name)
    [parsing_tc.add_step([k.name] + k.args) for k in test.keywords]
tc.save()
