Environment variables

Environment variables provide another way to specify configuration options and credentials.

YourBase Test Acceleration supports the following environment variables. You should set them in same way you set other environment variables for your deployment.


YOURBASE_ACCEPT_TOS

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When set, YourBase Test Acceleration will consider the terms of service permanently accepted for your organization, and will not output terms of service agreement prompts or info messages. This is helpful, for example, when rolling out YourBase Test Acceleration to CI for an organization.


YOURBASE_ACTIVE_COHORT

  • Type: integer
  • Range: [1, $YOURBASE_COHORT_COUNT]
  • Default: 1

When set alongside YOURBASE_COHORT_COUNT, tells YourBase Test Acceleration the cohort ID to run. Used for sharded or otherwise parallelized test suites.

See here to learn to use this in your parallelized test-suite.


YOURBASE_COHORT_COUNT

  • Type: integer
  • Range: [1, ∞)
  • Default: 1

When set alongside YOURBASE_ACTIVE_COHORT, tells YourBase Test Acceleration how many cohorts the tests should be split into.

This pair of settings lets YourBase Test Acceleration work with your existing sharding or parallelization setup. See here to learn to use it in your parallelized test setup.


YOURBASE_LICENSE_KEY

  • Type: opaque string
  • Default: (unset)

When set to a valid license key, YourBase Test Acceleration will be unlocked for use after the end of the free trial. Email hi@yourbase.io to obtain a license key.


YOURBASE_OBSERVATION_MODE

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will not skip tests, and instead, only record the duration and outcome of each test it believes should be skipped.

When this setting is off, YourBase Test Acceleration will optimize your test run-time as usual.

It’s useful to turn this setting on when you’re testing YourBase Test Acceleration before taking it live with your codebase. Learn more about how to use the Observation mode here.


YOURBASE_REMOTE_CACHE

  • Type: URI
  • Default: (unset)

When set, this synchronizes dependency graphs generated from clean working trees to the given remote location.—dependency graphs generated from dirty working trees will not be synchronized as they can poison the cache. Use YOURBASE_SYNC_DIRTY to override this behavior.

# Without a key prefix
export YOURBASE_REMOTE_CACHE=s3://my-bucket-name
# With a key prefix
export YOURBASE_REMOTE_CACHE=s3://my-bucket-name/my/key/prefix

This setting is recommended for use when using YourBase Test Acceleration in CI, as the filesystem will not be a dependable store for dependency graphs. Learn to set up a shared dependency graph in your CI here.


YOURBASE_AWS_ACCESS_KEY_ID

  • Type: AWS access key ID
  • Default: (unset)

When set alongside YOURBASE_AWS_SECRET_ACCESS_KEY, forces YourBase Test Acceleration to use these credentials over system credentials when interacting with AWS.

These environment variables are recommended for use if your AWS system credentials are fudged for the sake of your tests. Learn to use this YourBase Test Acceleration specific AWS environment variables here.


YOURBASE_AWS_SECRET_ACCESS_KEY

  • Type: AWS secret access key
  • Default: (unset)

When set alongside YOURBASE_AWS_ACCESS_KEY_ID, forces YourBase Test Acceleration to use these credentials over AWS system credentials when interacting with AWS.

These environment variables are recommended for use if your system credentials are mocked for the sake of your tests. Learn to use this YourBase Test Acceleration specific AWS environment variables here


YOURBASE_DEBUG

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will report significantly more internal information to stdout, stderr, and XDG (see the file returned by this expression):

echo ${XDG_STATE_HOME-~/.local/state}/yourbase/python.log

This setting is most beneficial when collaborating with the YourBase Test Acceleration team to debug issues.


YOURBASE_GENERATE_COVERAGE

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will generate a coverage database including coverage data from previous runs.

This setting will remove the need to enable coverage via the standard pytest or coverage commandline options.


YOURBASE_DISABLE

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will not load.

Enabling this setting and then manually attaching to a test framework using yourbase.attach produces undefined behavior.


YOURBASE_IGNORE_LOCAL_CACHE

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will not look in the local filesystem for a dependency graph.

If you’ve set YOURBASE_REMOTE_CACHE to a valid location, YourBase Test Acceleration will look up and synchronize the dependency graph with the specified location.

Else, if YOURBASE_REMOTE_CACHE is not set, YourBase Test Acceleration will do a cold run of your tests—it will run all the tests since it won’t be able to find any dependency graph.

This setting can be used if the local cache is expected to be poisoned. For instance, this can happen if cohorting is used against a local cache.


YOURBASE_SYNC_DIRTY

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will synchronize dependency graphs even if the Git working tree is dirty.

This setting is not recommended for use when you run YourBase Test Acceleration locally, as it will poison the remote cache.

This setting is useful when you use YourBase Test Acceleration in CI. There it can help you overcome situations where you need your working tree to be dirty while building, and you know the dirtiness will not affect the dependency graph. If that situation does not apply to you, do not enable this setting.


YOURBASE_TELEMETRY

  • Type: bool (0, false, off, 1, true, on)
  • Default: on

When on, YourBase Test Acceleration will send anonymized telemetry data to api.yourbase.io over HTTPS for the purposes of improving the product. Note that, telemetry data never includes your code.

Turn this off if you want to opt out of sending usage statistics and error reports to YourBase Test Acceleration.

Learn more about telemetry data here.


YOURBASE_TIMID

  • Type: bool (0, false, off, 1, true, on)
  • Default: off

When on, YourBase Test Acceleration will use a slower tracing algorithm that is less prone to conflicts with other packages than the default.

We recommend reaching out to support@yourbase.io if you are encountering this scenario, and only enabling this if you experience issues with the default algorithm.


YOURBASE_WORKDIR

  • Type: path
  • Default: .

This is the directory that YourBase Test Acceleration treats as the project directory. Only the code in this directory, or one of its descendants, will be traced.

You usually do not need to change this, as it’s mainly for debugging purposes.
