@knapsack-pro/jest
Advanced tools
Knapsack Pro Jest splits Jest tests across CI nodes and makes sure that tests will run in optimal time on each CI node.
@knapsack-pro/jest runs your tests with Jest test runner and does dynamic tests allocation across parallel CI nodes using KnapsackPro.com Queue Mode to provide the fastest CI build time (optimal test suite timing).
Learn about Knapsack Pro Queue Mode in the video how to run tests with dynamic test suite split and learn what CI problems can be solved thanks to it.
Please ensure you have added jest package in your project package.json.
@knapsack-pro/jest uses jest version installed in your project.
For npm users:
$ npm install --save-dev @knapsack-pro/jest
For yarn users:
$ yarn add --dev @knapsack-pro/jest
Whenever you see npm in below steps you can use yarn there as well.
To get API token just sign up at KnapsackPro.com. Please add to your CI environment variables KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST. You can generate API token in user dashboard.
Next to your API token, you can find a link "Build metrics" where you can preview recorded CI builds. You will see yellow tips if something is not configured as expected. Refresh the page once you finish running tests to see new tips. You can also click "Show" on CI build to see details about particular CI build. Look for yellow tips suggesting what to change to ensure all works fine for your project.
(optional) Do you want to use "retry single failed parallel CI node" feature for your CI? For instance some of CI providers like Travis CI, Buildkite or Codeship allows you to retry only one of failed parallel CI node instead of retrying the whole CI build with all parallel CI nodes. If you want to be able to retry only single failed parallel CI node then you need to tell Knapsack Pro API to remember the way how test files where allocated across parallel CI nodes by adding to your CI environment variables KNAPSACK_PRO_FIXED_QUEUE_SPLIT=true.
The default is KNAPSACK_PRO_FIXED_QUEUE_SPLIT=false which means when you want to retry the whole failed CI build then a new dynamic test suite split will happen across all retried parallel CI nodes thanks to Knapsack Pro Queue Mode. Some people may prefer to retry the whole failed CI build with test files allocated across parallel CI nodes in the same order as it happend for the failed CI build - in such case you should set KNAPSACK_PRO_FIXED_QUEUE_SPLIT=true.
(optional) If one of the parallel CI nodes starts work very late after other parallel CI nodes already finished work.
Some of CI providers have a problem with starting parallel CI nodes as soon as possible. For instance, you have a fixed pool of parallel CI nodes shared with many CI builds and sometimes CI build has started work even the pool has not enough available parallel CI nodes at the moment. Another case is when the CI provider infrastructure is overloaded which can lead to some parallel CI nodes starting work later than others.
Do you have the CI server that does not start all parallel CI nodes at the same time and one of your parallel CI nodes will start work very late after all other parallel CI nodes already finished consuming tests from the Knapsack Pro Queue? In such a case, if you would use default KNAPSACK_PRO_FIXED_QUEUE_SPLIT=false then the very late CI node would start running all tests again based on a new Queue which means you would run test suite twice. This problem can happen if your test suite is very small and differences in the start time of parallel CI nodes are very big.
You should set KNAPSACK_PRO_FIXED_QUEUE_SPLIT=true to ensure the very late parallel CI node won't run tests again if the Queue was already consumed. The downside of this is that you won't be able to run 2nd CI build for the same set of values git commit/branch/ci node total number with a dynamic test suite split way if your CI provider does not expose unique CI build ID. Instead, the tests will be run assigned to the same parallel CI node indexes with the same order as it was recorded for the first time.
Knapsack Pro tries to detect CI build ID from the environment variables of your CI provider. Here you can check if your CI provider exposes CI build ID, see function ciNodeBuildId (example for Github Actions). If you CI provider won't provide CI build ID you can set KNAPSACK_PRO_CI_NODE_BUILD_ID (see next point).
(optional) @knapsack-pro/jest detects information about CI build from supported CI environment variables. When information like git branch name and git commit hash cannot be detect from CI environment variables then @knapsack-pro/jest will try to use git installed on CI machine to detect the infomation. If you don't have git installed then you should set the information using environment variables:
KNAPSACK_PRO_COMMIT_HASH - git commit hash (SHA1)KNAPSACK_PRO_BRANCH - git branch nameKNAPSACK_PRO_CI_NODE_BUILD_ID - a unique ID for your CI build. All parallel CI nodes being part of single CI build must have the same node build ID. Example how to generate node build ID: KNAPSACK_PRO_CI_NODE_BUILD_ID=$(openssl rand - base64 32).If you have test files in a non-default directory or you specify test files to run in Jest config file then you won't be able to run tests and you may see below error.
Response body:
{ errors: [ { test_files: [ 'parameter is required' ] } ] }
Please adjust KNAPSACK_PRO_TEST_FILE_PATTERN variable to match your test files directory structure to let Knapsack Pro detect all the test files you want to run in parallel. You can also exclude test files with KNAPSACK_PRO_TEST_FILE_EXCLUDE_PATTERN.
If you want to use Jest config file with @knapsack-pro/jest check this tip.
If you use --coverage flag for Jest to generate code coverage then to make it work please check how to generate code coverage for Jest with @knapsack-pro/jest in Queue Mode?
If you use jest-junit please check how to generate XML report using jest-junit with @knapsack-pro/jest in Queue Mode?
Please select your CI provider and follow instructions to run tests with @knapsack-pro/jest.
Example configuration for CircleCI 2.0 platform.
# ~/.circleci/config.yml
version: 2
jobs:
test:
docker:
- image: circleci/<language>:<version TAG>
parallelism: 2 # run 2 parallel CI nodes
steps:
- checkout
- run:
name: Run Jest tests with @knapsack-pro/jest using Knapsack Pro Queue Mode
command: $(npm bin)/knapsack-pro-jest
Please remember to add additional parallel containers for your project in CircleCI settings.
You can parallelize your CI build across virtual machines with travis matrix feature.
# .travis.yml
script:
- '$(npm bin)/knapsack-pro-jest'
env:
global:
- KNAPSACK_PRO_CI_NODE_TOTAL=2
# allows to be able to retry failed tests on one of parallel job (CI node)
- KNAPSACK_PRO_FIXED_QUEUE_SPLIT=true
jobs:
- KNAPSACK_PRO_CI_NODE_INDEX=0
- KNAPSACK_PRO_CI_NODE_INDEX=1
The configuration will generate matrix with 2 parallel jobs (2 parallel CI nodes):
# first CI node (first parallel job)
KNAPSACK_PRO_CI_NODE_TOTAL=2 KNAPSACK_PRO_CI_NODE_INDEX=0
# second CI node (second parallel job)
KNAPSACK_PRO_CI_NODE_TOTAL=2 KNAPSACK_PRO_CI_NODE_INDEX=1
More info about global and matrix ENV configuration in travis docs.
The only thing you need to do is to configure the parallelism parameter (number of parallel agents) in your build step and run the below command in your build:
$(npm bin)/knapsack-pro-jest
If you want to use Buildkite retry single agent feature to retry just failed tests on particular agent (CI node) then you should set KNAPSACK_PRO_FIXED_QUEUE_SPLIT=true.

Here you can find article how to set up a new pipeline for your project in Buildkite and configure Knapsack Pro and 2 example repositories for Ruby/Rails projects:
When using the docker-compose plugin on Buildkite, you have to tell it which environment variables to pass to the docker container. Thanks to it Knapsack Pro can detect info about CI build like commit, branch name, amount of parallel nodes.
steps:
- label: 'Test'
parallelism: 2
plugins:
- docker-compose#3.0.3:
run: app
command: $(npm bin)/knapsack-pro-jest
config: docker-compose.test.yml
env:
- BUILDKITE_PARALLEL_JOB_COUNT
- BUILDKITE_PARALLEL_JOB
- BUILDKITE_BUILD_NUMBER
- BUILDKITE_COMMIT
- BUILDKITE_BRANCH
Codeship does not provide parallel jobs environment variables so you will have to define KNAPSACK_PRO_CI_NODE_TOTAL and KNAPSACK_PRO_CI_NODE_INDEX for each parallel test pipeline. Below is an example for 2 parallel test pipelines.
Configure test pipelines (1/2 used)
# first CI node running in parallel
KNAPSACK_PRO_CI_NODE_TOTAL=2 KNAPSACK_PRO_CI_NODE_INDEX=0 $(npm bin)/knapsack-pro-jest
Configure test pipelines (2/2 used)
# second CI node running in parallel
KNAPSACK_PRO_CI_NODE_TOTAL=2 KNAPSACK_PRO_CI_NODE_INDEX=1 $(npm bin)/knapsack-pro-jest
Remember to add API token KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST to Environment page of your project settings in Codeship.
CodeShip uses the same build number if you restart a build. Because of that you need to set KNAPSACK_PRO_FIXED_QUEUE_SPLIT=true in order to be able to restart CI build.
You can parallelize your tests on Heroku CI by configuring app.json for your project.
You can set how many parallel dynos with tests you want to run with quantity value.
Use test key to run tests with @knapsack-pro/jest as shown in below example.
You need to specify also the environment variable KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST with API token for Knapsack Pro.
For any sensitive environment variables (like Knapsack Pro API token) that you do not want commited in your app.json manifest, you can add them to your pipeline’s Heroku CI settings.
# app.json
{
"environments": {
"test": {
"formation": {
"test": {
"quantity": 2
}
},
"addons": [
"heroku-postgresql"
],
"scripts": {
"test": "$(npm bin)/knapsack-pro-jest"
},
"env": {
"KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST": "example"
}
}
}
}
If you would like to run multiple Knapsack Pro commands for different test runners on Heroku CI please follow tips.
Note the Heroku CI Parallel Test Runs are in Beta and you may need to ask Heroku support to enable it for your project.
You can learn more about Heroku CI.
Solano CI does not provide parallel jobs environment variables so you will have to define KNAPSACK_PRO_CI_NODE_TOTAL and KNAPSACK_PRO_CI_NODE_INDEX for each parallel job running as part of the same CI build.

# Thread 1
$(npm bin)/knapsack-pro-jest
# Thread 2
$(npm bin)/knapsack-pro-jest
Tests will be split across 2 parallel threads.
Please remember to set up API token KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST as global environment.
The only thing you need to do is to configure number of parallel CI nodes for your project by using matrix modification. See example for 2 parallel CI nodes.

@knapsack-pro/jest supports environment variables provided by Codefresh.io to run your tests. You have to define a few things in .codefresh/codefresh.yml config file.
KNAPSACK_PRO_TEST_SUITE_TOKEN_JEST in Codefresh dashboard, see left menu Pipelines -> settings (cog icon next to the pipeline) -> Variables tab (see a vertical menu on the right side)../.codefresh/codefresh.yml).KNAPSACK_PRO_CI_NODE_TOTAL environment variable in .codefresh/codefresh.yml file.matrix section you listed all KNAPSACK_PRO_CI_NODE_INDEX environment variables with a value from 0 to KNAPSACK_PRO_CI_NODE_TOTAL-1. Codefresh will generate a matrix of parallel jobs where each job has a different value for KNAPSACK_PRO_CI_NODE_INDEX. Thanks to that Knapsack Pro knows what tests should be run on each parallel job.Below you can find Codefresh YAML config and Test.Dockerfile used by Codefresh to run the project and Jest test suite inside of Docker container.

:heavy_exclamation_mark: NEW: Up to date FAQ for Knapsack Pro Jest can be found here.
OLD: This README also contains FAQ questions but we keep adding new info only to our new FAQ page mentioned above.
We keep this old FAQ in README to not break old links spread across the web.
This project depends on @knapsack-pro/core. Please check the FAQ for @knapsack-pro/core to learn more about core features available to you.
You can set KNAPSACK_PRO_TEST_FILE_PATTERN="{**/__tests__/**/*.js?(x),**/?(*.)(spec|test).js?(x)}" and change pattern to match your directory with test files. You can use glob pattern.
@knapsack-pro/jest by default rejects tests inside of node_modules directory. If your pattern set by KNAPSACK_PRO_TEST_FILE_PATTERN matches test file paths within node_modules then those test file paths won't be run.
If you want to use a few patterns you can do it as shown above KNAPSACK_PRO_TEST_FILE_PATTERN="{pattern_1,pattern_2}".
If you want to use single pattern then you can do KNAPSACK_PRO_TEST_FILE_PATTERN="__tests__/**/*.test.js".
You can set KNAPSACK_PRO_TEST_FILE_EXCLUDE_PATTERN which define a glob pattern to exclude tests similar to Jest testPathIgnorePatterns parameter. Note testPathIgnorePatterns uses regexp pattern while KNAPSACK_PRO_TEST_FILE_EXCLUDE_PATTERN uses glob pattern.
UP TO DATE ANSWER: https://knapsackpro.com/faq/question/how-to-pass-command-line-options-to-jest
You can pass command line options to Jest by just passing them to @knapsack-pro/jest. See example:
$(npm bin)/knapsack-pro-jest --debug
You can find list of Jest CLI options here.
