CRISPResso2_tests

A repository for testing that is too large (or too private) to be kept in their respective repositories.

CRISPResso2 Thorough Integration Tests

To run the integration tests for CRISPResso2 make sure that the CRISPRESSO2_DIR variable in the Makefile is set to the correct directory where the CRISPResso2 repository is (by default it is set to ../CRISPResso2). Then to run only the integration tests you can issue make all test and it will run the tests and compare the output.

Furthermore, the running times of each integration test will be checked and if there is a difference > 10% in the two times, it will be reported.

For improved diff output, run pip install ydiff and the diffs will be colorized and side by side.

How can I run a test?

As explained above, to run all of the tests use:

make all

To run all the tests and check all files for differences use the test option:

make all test

If you want to skip differences in html files you can run:

make all test skip_html

You can also select a single command to run, like this:

make basic

Note: this will only run the CRISPResso command, it will not check the output files for differences.

If you want to run a single command and check it for differences, use the test option, like this:

make basic test

By default, tests will only print command output in the case of an error. To force print output for any test use the print option, like this:

make basic print

How can I update the expected results for a test?

If you run a test and there are differences, you can run the command:

python test_manager.py update <actual CRISPResso results directory> <expected CRISPResso results directory>

This will show you what is different in the files, and then you can select whether you want them copied over or not.

You can also run it through make:

make <test case> update

The above will prompt you to confirm if you want each change.

If you are very confident in each change, you can use update-all:

make <test case> update-all

This will automatically update the files for you, then you can review the changes in git. Use this wisely!

How can I add a test?

If you want to add a test, you can run the command:

python test_manager.py add <actual CRISPResso results directory>

This will get the command that you used to run and add it to the Makefile, it will also copy over the files into the cli_integration_tests/expected_results directory and (try) to copy over the input files into the appropriate places. As with all semi-automated tools, you should most definitely check the work of the program before committing it.

Selenium Testing

In order to test the web UI using Selenium there are several pre-requisites:

• You must have Docker installed
• Use Docker to build the C2Web Docker image with the name crispresso2web
  • e.g. docker build -t crispresso2web .
• You must also have Google Chrome installed, the most recently version is best.
• In the environment you are using the following libraries must be installed (followed by conda examples).
  • Selenium conda install -c conda-forge selenium
  • webdriver_manager conda install webdriver-manager

The test can be run using make web_ui

Warning: The tests will fail if the pages fail to load within a buffer period.
