This repository provides data and input files used for testing PypeIt.
To install, run:
git clone https://github.com/pypeit/PypeIt-development-suite.gitThis pulls the versioned files into a directory called
PypeIt-development-suite. Both the testing script in this repo and
the tests that are included with the PypeIt code expect an environmental
variable that points to this directory. For example,
If you use c-shell, add the following to your
~/.cshrc:setenv PYPEIT_DEV ${HOME}/PypeIt-development-suiteIf you use bash, add the following to your
~/.bashrcor~/.bash_profile:export PYPEIT_DEV=${HOME}/PypeIt-development-suite
Given its volume, this repo does not contain the raw data. Instead the raw test data are hosted by in a Google Drive.
The easiest way to access the development suite data is download and use Google Drive for desktop. Google Drive for desktop is a Dropbox-like application that syncs your Google Drive with a local directory on your machine.
Using Google Drive for desktop, the you will be able to access the development suite data at the path:
/Volumes/GoogleDrive/My\ Drive/PypeIt-development-suite/
If PypeIt-development-suite does not appear under My Drive, go to the Google Drive web interface, find it under Shared with me,
right click it, and select Add shortcut to drive.
If you cannot or would rather not use Google Drive for desktop, you can simply download the appropriate files directly using the Google Drive web interface (although this can be a bit onerous and does not keep in sync with the remote Team Drive). Alternately you can use rclone to manually copy or sync with the Google Drive.
The Google Drive contains two directories that should be accessible for
testing PypeIt (see below): RAW_DATA, and CALIBS.
If you download the data directly from the Google Drive, place them in your
PypeIt-development-suitedirectory. Make sure that you *do not* add these directories to the repo!If you're using Google File Stream, add symlinks to your
PypeIt-development-suitedirectory as follows (be sure to include the in the MyDrive otherwise the space in "My Drive" will cause problems):cd $PYPEIT_DEV ln -s /Volumes/GoogleDrive/My\ Drive/PypeIt-development-suite/RAW_DATA RAW_DATA ln -s /Volumes/GoogleDrive/My\ Drive/PypeIt-development-suite/CALIBS CALIBS
This suite includes several examples of the PypeIt data reduction process for some of the supported instruments.
If you have PypeIt installed, you
should be able to run the tests in this directory using the
pypeit_test script. It has one required argument, the type of tests to run.
$ $PYPEIT_DEV/pypeit_test allThe above runs all pypeit tests, including the unit tests in the PypeIt installation. To run a subset of tests you can specify one or more test type. For example:
# Run the non-pytest tests, similar to develop in prior versions
$ $PYPEIT_DEV/pypeit_test reduce afterburn ql
# Run reduce tests followed by the vet pytest tests
$ $PYPEIT_DEV/pypeit_test reduce vetAll of the supported test test types are shown in the table below.
| Test Type | Description |
|---|---|
| pypeit_tests | Runs the pytest tests installed with PypeIt in pypeit/tests. These tests are self contained and can run in CI. |
| unit | Runs the pytest tests installed in $PYPEIT_DEV/unit. These tests require the RAW_DATA directory. |
| reduce | Runs the reduction tests that call run_pypeit directly. |
| afterburn | Runs the PypeIt tests that directly call PypeIt post-reduction tools (e.g. flux calibration, coadding, etc). |
| ql | Runs the Quick Look tests. |
| vet | Runs the pytest tests that verify the results from earlier PypeIt tests. |
| all | Runs all of the above, in the order listed above. |
| list | This does not run any tests, instead it lists all of the supported instruments and setups. (See below). |
The unit and vet tests can also be run directly using pytest. For example:
$ cd $PYPEIT_DEV
# Run all dev-suite unit tests
$ pytest unit_tests
# Run all dev-suite vet tests
$ pytest vet_tests
# Run the script tests in both unit_tests and vet_tests
$ pytest unit_tests/test_scripts.py vet_tests/test_scripts.pySee the pytest docs for more information on running pytest.
The -i and -s options to pypeit_test can be used to select multiple
instruments and setups to test. Setups can be specified in conjunction with
an instrument or by using a / between instrument and setup name. For example:
# Run all of pytest tests and all of the shane_kast_blue and shane_kast_red tests
cd $PYPEIT_DEV
$ ./pypeit_test all -i shane_kast_blue shane_kast_red
# Run one reduce test from shane_kast_blue and shane_kast_red respectively
$ ./pypeit_test reduce -i shane_kast_blue shane_kast_red -s 600_4310_d55 600_7500_d57
# Run the same tests as above, using the / syntax
$ ./pypeit_test reduce -s shane_kast_blue/600_4310_d55 shane_kast_red/600_7500_d57Run pypeit_test list to see a list of all supported instruments and setups.
A test report can be generated using the -r option, for example:
$PYPEIT_DEV/pypeit_test all -r test_report.txtThe contents of the report contain complete pytest output and additional information about the test setups run. Below is an example of some of the output:

Coverage . To do this add
--coverage <coverage report file> to the pypeit_test command:
$ cd $PYPEIT_DEV
$ ./pypeit_test all --coverage coverage_report_file.txtThe coverage report contains a file by file list of the coverage information, including missed lines. It ends with a summary of the total code coverage.
The unit tests, and deprecated sections of the PypeIt code base are omitted.

./pypeit_test -t 2 allThe number of threads that can be run depends on the amount of memory available. Based on testing, the memory requirements of the devsuite are:
|
Memory Usage |
|---|---|
| 1 | 20 GiB |
| 2 | 40 GiB |
| 4 | 58 GiB |
| 6 | 78 GiB |
| 8 | 98 GiB |
| 12 | 133 GiB |
| 16 | 148 GiB |
For systems with more virtual CPUs than physical CPU cores (i.e. Hyperthreading) the number of threads should not exceed the number of physical cores, or else there could be a performance hit as threads compete for resources.
To keep all cpus active as long as possible pypeit_test runs the
slowest tests first. To do this it needs the test_priority_list file
which contains a list of all the test setups ordered from slowest to
fastest. This file is re-written everytime a run of the full test suite
passes, and should be kept up to date by periodically pushing it to git.
The pytest portion of the dev-suite currently cannot be run in parallel.
Some of the tests in the dev-suite will start GUI applications. To run
in a headless environment where this isn't possible, QT must still be
installed. To do so, first install PypeIt with QT5 support, as
documented here. Next
install the correct QT package for the OS.
| OS Distribution | Package name |
|---|---|
| Ubuntu 21.04 | qt5-default |
| Ubuntu 22.04 | qtbase5-dev |
| Centos 7 | qt5-qtbase-devel |
Finally, set the QT_QPA_PLATFORM environment variable to
offscreen. There is a convenience file named
source_headless_test.sh that will do this. For example:
source $PYPEIT_DEV/source_headless_test.shThe dev-suite can be run in the Nautilus cluster.
To generate the YAML for a dev-suite job, use gen_kube_devsuite. If needed,
a specific branch of both the PypeIt repository and the Pypeit-development-suite
repository can be chosen using -p and -d respectively. These default to
develop if not specified. The YAML file can then be ran using kubectl.
For example to run using the pypeit_branch on the PypeIt repo and the devsuite_branch on the PypeIt-development-suite repo:
$ cd $PYPEIT_DEV/nauitilus
$ ./gen_kube_devsuite devsuite-job-name devsuite_job_file.yml -p pypeit_branch -d devsuite_branch
$ kubectl create -f devsuite_job_file.ymlThe results of the dev-suite are copied to Nautilus S3 under
s3://pypeit/Reports/. And can be retrieved using the AWS CLI as
follows:
aws --endpoint https://s3-west.nrp-nautilus.io s3 cp s3://pypeit/Reports/devsuite-job-name.report .rclone can also be used access the Nautilus S3 storage. When
configuring use https://s3-west.nrp-nautilus.io as the endpoint.
The default job created by gen_kube_devsuite runs directly from git. However it can be changed to run
by building a new PypeIt package and installing from that, simulating what a user would get when
installing from PyPi. This is enabled with the --from_wheel or -w option.
gen_kube_devsuite has additional code for generating coverage
information and the test priority list. If --coverage and
--priority_list are used, these files are also copied to S3:
$ ./gen_kube_devsuite coverage-job-name coverage_job_file.yml --coverage
$ ./gen_kube_devsuite priority-job-name priority_job_file.yml --priority_list
$ kubectl create -f coverage_job_file.yml
$ kubectl create -f priority_job_file.yml
$ # Wait several hours
$ export ENDPOINT=https://s3-west.nrp-nautilus.io
$ aws --endpoint $ENDPOINT s3 cp s3://pypeit/Reports coverage-job-name.report .
$ aws --endpoint $ENDPOINT s3 cp s3://pypeit/Reports/priority-job-name.report .
$ aws --endpoint $ENDPOINT s3 cp s3://pypeit/Reports/coverage-job-name.coverage.report .
$ aws --endpoint $ENDPOINT s3 cp s3://pypeit/Reports/priority-job-name.test_priority_list .Notice that --coverage can affect the performance of tests, so it's best
not to run it and --priority_list together.
To monitor a test in Nautilus as it is running, the logs can be tailed:
$ kubectl get pods
NAME READY STATUS RESTARTS
devsuite-job-name--1-fpjxw 1/1 RUNNING 0
$ kubectl logs -f devsuite-job-name--1-fpjxwAdditionally they can be monitored with the Nautilus Grafana page.
By default gen_kube_devsuite creates a job using a the latest Python container
available on Docker Hub. It also supports running with different python versions by
selecting a different container. For example:
$ ./gen_kube_devsuite devsuite-python3.11-job devsuite-python3.11-job.yml --container python3.11Any of the standard python images in docker hub can be used. To use a different container the full download path must be given. For example:
$ ./gen_kube_devsuite devsuite-ubuntu-job devsuite-ubuntu-job.yml --container docker.io/library/ubuntu:22.04$ $PYPEIT_DEV/pypeit_test -h

Run pypeit tests on a set of instruments. Typical call for testing pypeit when
developing new code is `./pypeit_test all`. Execution requires you to have a
PYPEIT_DEV environmental variable, pointing to the top-level directory of the
dev-suite repository (typically the location of this script). Raw data for
testing is expected to be at ${PYPEIT_DEV}/RAW_DATA. To run all tests for the
supported instruments, use 'all'. To only run the basic reductions, use
'reduce'. To only run the tests that use the results of the reductions, use
'afterburn''. Use 'list' to view all supported setups.
positional arguments:
