Cypress based test framework for LibreOffice Online
====================================================
Installation
------------------
You need to have run configure with the --enable-cypress option.
In a normal desktop environment you only need to install npm
packages for running cypress tests. This is done by the build
system, so running 'make check' will do the basic installation.
https://docs.cypress.io/guides/getting-started/installing-cypress.html#npm-install
For CI you might need to install some additional dependencies:
https://docs.cypress.io/guides/guides/continuous-integration.html#Dependencies
Running tests
------------------
All tests are part of the make check build. So you can
just execute it from the root folder or under the
cypress_test folder to run cypress tests only.
make check
IMPORTANT: Before stepping under cypress_test folder
and running any command listed here, make sure you've
done a top-level make, so everything is up-to-date.
Running commands from under cypress_test folder won't
trigger a rebuild.
To run cypress test cases selectively, you need to
go in to the cypress_test folder first and run one of
the following commands.
To run all desktop tests:
make check-desktop
To run all mobile tests:
make check-mobile
To run one specific test suite of desktop tests,
use spec argument with a relative path to
cypress_test/integration_tests/desktop/:
make check-desktop spec=writer/form_field_spec.js
To run one specific test suite of mobile tests,
use spec argument with a relative path to
cypress_test/integration_tests/mobile/:
make check-mobile spec=writer/toolbar_spec.js
Running one specific test
------------------
To run one test case of a test suite you can use Mocha's
'only' feature. Just replace the it(...) function with
it.only(...) in the spec file for the selected test case
and run the test suite using the spec parameter.
For example, to run the test with title 'Apply font name.'
inside apply_font_spec.js file, you need to add it.only():
- it('Apply font name.', function() {
+ it.only('Apply font name.', function() {
Then run the test suite with:
make check-mobile spec=writer/apply_font_spec.js
Or open the test suite in the interactive test runner:
make run-mobile spec=writer/apply_font_spec.js
Openning interactive test runner
----------------------------------
Cypress has an interactive test runner application which
runs the test in the browser. So you can see the result of
the different steps your test makes in the browser. It's useful
during writing new tests or checking why an existing
test fails.
https://docs.cypress.io/guides/core-concepts/test-runner.html
To open desktop tests in the test runner:
make run-desktop
To open mobile tests in the test runner:
make run-mobile
To open one specific test suite of desktop tests,
use spec argument with a relative path to
cypress_test/integration_tests/desktop/:
make run-desktop spec=writer/form_field_spec.js
To open one specific test suite of mobile tests,
use spec argument with a relative path to
cypress_test/integration_tests/mobile/:
make run-mobile spec=writer/toolbar_spec.js
During the build we run the tests with Chrome browser, so make sure
you select Chrome browser on the GUI while checking tests.
We are using different configuration and environment variables for
mobile and desktop tests, that's why there are two separate commands
for them and there is no option to open all the tests in the
test runner.
Known issues
------------
1. Different builddir and sourcedir with symlinks.
Cypress has an issue with symlinks:
https://github.com/cypress-io/cypress/issues/3482
We use the related feature only when the build directory
is different from the source directory. So to avoid this
issue with the supportFile, you should build in the source
directory or you should avoid symlinks in the path of the
build directory.
Code coverage
------------
We use nyc to instrument the code and then cypress code coverage
plugin is used to generate coverage numbers. This workflow
is called by the following command:
make run-cov
The output is put under cypress_test/covarage folder.
Open the cypress_test/covarage/lcov-report/index.html
file to get the summary report.
The make command above touches the source files under
loleaflet/dist/src folder, so after testing the coverage
doing a clean build is a good idea (e.g. make clean).
