Let’s assume that in the country package openfisca_france
, net_salary
is always 80% of gross_salary
.
test.yaml:
- name: "Basic test"
period: 2015
input_variables:
gross_salary: 2000
output_variables:
net_salary: 2000 * 0.8
Command line:
openfisca-run-test -c openfisca_france test.yaml
# Success
openfisca-run-test test.yaml
# Success: the country package is automatically detected.
# May fail if several country packages are installed in your environment.
# In that case, specify which package to use with the --country_package option
test_2.yaml:
- name: "Test defining a relative error margin"
period: 2015
relative_error_margin: 0.05
input_variables:
gross_salary: 1000
output_variables:
net_salary: 780 # the right value is 800
- name: "Test defining an absolute error margin"
absolute_error_margin: 10
period: 2015
input_variables:
gross_salary: 1000
output_variables:
net_salary: 790 # the right value is 800
test_3.yaml:
- name: "Test not defining any error margin"
period: 2015
input_variables:
gross_salary: 1000
output_variables:
net_salary: 795 # the right value is 800
Command line:
openfisca-run-test test_2.yaml
# Success: the test pass, as the actual results are within the error margins
openfisca-run-test test_3.yaml
# Failure: the test does not pass, as its error margin is by default 0
test_4.yaml:
- name: "Test containing the word openfisca in its name"
period: 2015
input_variables:
gross_salary: 1000
output_variables:
net_salary: 800
- name: "Test that contains the magic word in its keywords"
keywords:
- some keyword
- openfisca
period: 2015
input_variables:
gross_salary: 1000
output_variables:
net_salary: 800
- name: "Some other test that fails"
period: 2015
input_variables:
gross_salary: 1000
output_variables:
net_salary: 0
Command line:
openfisca-run-test test_4.yaml
# Failure: the third test does not pass
openfisca-run-test -n openfisca test_4.yaml
# Success: the third test is not executed, as it doesn't contain the word 'openfisca'
Note that if a test file name contains the name filter, all the inner tests will be executed.
Let’s now assume an extension to openfisca_france
, openfisca_paris
is installed on our system, defines the variable paris_housing_benefit
, and that this variable is worth 200
if net_salary
is 0
.
test_5.yaml:
- name: "Test using an extension"
period: 2015
input_variables:
net_salary: 0
output_variables:
paris_housing_benefit: 200
Command line:
openfisca-run-test test_5.yaml
# Failure: the test returns an error:
# the country package openfisca_france does not references a variable named paris_housing_benefit
openfisca-run-test -e openfisca_paris test_5.yaml
# Success: The test passes, as the extension is loaded in the tax benefit system before running the test
Let’s assume that I want to test a reform that lowers net_salary
to 60% of gross_salary
(instead of 80% in the regular openfisca_france
).
This reform is called increase_cotisation
and available in the python module openfisca_france.reforms.increase_cotisation
.
test_6.yaml:
- name: "Test on a reform"
period: 2015
input_variables:
gross_salary: 1000
output_variables:
net_salary: 600
Command line:
openfisca-run-test test_6.yaml
# Failure: the test does not pass, as the regular openfisca_france is used
openfisca-run-test -r openfisca_france.reforms.increase_cotisation.increase_cotisation test_5.yaml
# Success: The test passes, as the increase_cotisation reform is applied
