* doc: build first to avoid not found deps issues * fix: Remove XMLHttpRequest usage XMLHttpRequest API is deprecated and not available in browser extensions. Replace the culprit dependency with a more modern one. Some options are removed. The assumption is that nobody uses them. It can always be added if a developer wants the flexibility. * test: simplify test The test focus on testing DNS Discovery, there is no need to also have a nwaku local node for bootstrap. Bootstrap on nwaku local node is used in many other tests.
Description
This package contains tests for the js-waku library.
Pre-requisites
Some of the tests from this package require a running nwaku or go-waku node. These nodes are setup to be run in a docker container.
Therefore, you need to have docker installed on your machine to run the tests.
Running interop tests
-
The tests by default run against an
nwakunode with the image name specified innwaku.tsandpackages/tests/package.json. The tests can be run against a different image by setting the environment variableWAKUNODE_IMAGEto the desired image. -
The tests can be run against a
go-wakunode by setting the environment variableWAKUNODE_IMAGEto the desiredgo-wakuimage.-
Whatever
WAKUNODE_IMAGEis set to, the tests will run against that image. If the image is not available locally, the tests will pull the image from the docker hub. You can run the tests by running the following command:WAKUNODE_IMAGE=explicit-image-name npm run test:nodeOr against the default docker image by running:
npm run test:node
-
-
You can also run the tests against a local
nwakuorgo-wakunode by setting the environment variableWAKUNODE_IMAGEto the name of the image. The tests will then run against the local image.-
For example, to run the tests against a local checkout of
nwakuorgo-waku, build the image first manually. You can build the image by running the following command:docker build path-to-dockerfile -t image-nameThen, you can run the tests by running the following command:
WAKUNODE_IMAGE=image-name npm run test:node
-
-
Locally, tests are executed serially, allowing the use of .only for focused testing. If you wish to run all tests locally and expedite the process, you can enable parallel execution in the Mocha configuration.
Running tests in the CI
- Tests are being run on standard Ubuntu GitHub Actions instances.
- To speed up execution, we run tests in parallel. After numerous attempts, we determined that using 6 threads strikes the best balance between execution speed and test reliability. Using more than this doesn't significantly decrease execution time and might even slow it down.
- To address occasional test flakiness, primarily due to Docker containers starting and stopping for each test and the concurrent execution of tests, we utilize the Mocha retry mechanism.
