Configuring Your TestCafe Tests
saucectl
relies on a YAML specification file to determine exactly which tests to run and how to run them. To customize saucectl
to run your TestCafe tests, simply modify the properties of the YAML file accordingly. This page defines each of the configuration properties specific to running TestCafe tests.
Setting an Alternative Configuration File
By default, saucectl
looks for the config.yml
file in the .sauce
folder of your project root, but you can actually specify a different file, or if you are using multiple frameworks or need to configure different sets of tests to run separately, you may choose to have multiple configuration files that you can direct saucectl
to reference as necessary.
Use the following configuration at runtime to direct saucectl
to use any configuration file you choose:
saucectl run -c ./path/to/{config-file}.yml
While you can use multiple files of different names or locations to specify your configurations, each file must be a *.yml
and follow the saucectl
syntax. Our IDE Integrations (e.g., Visual Studio Code) can help you out by validating the YAML files and provide handy suggestions, so make sure to check them out!
Example Configuration
loading...
Each of the properties supported for running TestCafe tests through saucectl
is defined below.
apiVersion
| REQUIRED | STRING |
Identifies the version of the underlying configuration schema. At this time, v1alpha
is the only supported value.
apiVersion: v1alpha
kind
| REQUIRED | STRING/ENUM |
Specifies which framework is associated with the automation tests configured in this specification.
kind: testcafe
showConsoleLog
| OPTIONAL | BOOLEAN |
Controls whether the contents of console.log
are always shown in the local output of saucectl. By default (false), console.log
is only shown for failed suites.
showConsoleLog: true
defaults
| OPTIONAL | OBJECT |
Specifies any default settings for the project.
defaults:
timeout: 15m
timeout
| OPTIONAL | DURATION |
Instructs how long (in ms
, s
, m
, or h
) saucectl
should wait for each suite to complete. You can override this setting for individual suites using the timeout
setting within the suites
object. If not set, the default value is 0
(unlimited).
timeout: 15m
sauce
| OPTIONAL | OBJECT |
The parent property containing all settings related to how tests are run and identified in the Sauce Labs platform.
sauce:
region: eu-central-1
metadata:
tags:
- e2e
- release team
- other tag
build: Release $CI_COMMIT_SHORT_SHA
concurrency: 10
region
| OPTIONAL | STRING/ENUM |
Specifies through which Sauce Labs data center tests will run. Valid values are: us-west-1
or eu-central-1
.
region: eu-central-1
metadata
| OPTIONAL | OBJECT |
The set of properties that allows you to provide additional information about your project that helps you distinguish it in the various environments in which it is used and reviewed, and also helps you apply filters to easily isolate tests based on metrics that are meaningful to you, as shown in the following example:
metadata:
build: RC 10.4.a
tags:
- e2e
- release team
- beta
- featurex
concurrency
| OPTIONAL | INTEGER |
Sets the maximum number of suites to execute at the same time. If the test defines more suites than the max, excess suites are queued and run in order as each suite completes.
For tests running on Sauce, set this value to equal or less than your Sauce concurrency allowance, as setting a higher value may result in jobs dropped by the server.
concurrency: 5
Alternatively, you can override the file setting at runtime by setting the concurrency flag as an inline parameter of the saucectl run
command:
saucectl run --ccy 5
retries
| OPTIONAL | INTEGER |
Sets the number of times to retry a failed suite. For more settings, you can refer to passThreshold.
retries: 1
Alternatively, you can override the file setting at runtime by setting the retries flag as an inline parameter of the saucectl run
command:
saucectl run --retries 1
tunnel
| OPTIONAL | OBJECT |
saucectl
supports using Sauce Connect to establish a secure connection with Sauce Labs. To do so, launch a tunnel; then provide the name and owner (if applicable) in this property.

: Only accessible to people with a valid link.team
: (Default) Only accessible to people under the same root account as you.private
: Only you (the owner) will be able to view assets and test results page.
sauce:
visibility: private
launchOrder
| OPTIONAL | STRING |
Specifies the execution order for your test suites. When set to fail rate
, test suites with the highest failure rate will execute first. If unspecified, test suites will execute in the order in which they are written in the configuration file.
sauce:
launchOrder: fail rate
env
| OPTIONAL | OBJECT |
A property containing one or more environment variables that are global for all tests suites in this configuration. Values set in this global property will overwrite values set for the same environment variables set at the suite level.
env:
hello: world
my_var: $MY_VAR # You can also pass through existing environment variables through parameter expansion
Environment variables set with the saucectl --env
flag will overwrite those specified in the sauce config file.
The order of precedence is as follows: --env flag > root-level environment variables > suite-level environment variables.
rootDir
| REQUIRED | OBJECT |
The directory of files that need to be bundled and uploaded for the tests to run. Ignores what is specified in .sauceignore
. See Tailoring Your Test File Bundle for more details. The following examples show the different relative options for setting this value.
rootDir: "./" # Use the current directory
rootDir: "packages/subpackage" # Some other package from within a monorepo
Only the files contained within rootDir
will be available during the tests. Any reference to a file that is not included in rootDir
will make the tests fail.
npm
| OPTIONAL | OBJECT |
A parent property specifying the configuration details for any npm
dependencies. Packages listed are installed in the environment prior to your tests executing.

"@babel/preset-typescript": "7.12"
"@testcafe/react": "^5.0.1"
registry
| OPTIONAL | STRING |
This setting is supported up to TestCafe 2.6.2. For newer versions, use registries
.
Specifies the location of the npm registry source. If the registry source is a private address and you are running tests on Sauce Cloud, you can provide access to the registry source using Sauce Connect.
registry: https://registry.npmjs.org
registries
| OPTIONAL | ARRAY |
Specifies the location of the npm registry, scope, and credentials. If the registry is inside a private network, you must establish a tunnel using Sauce Connect.
registries:

packages
| OPTIONAL | OBJECT |
Specifies any npm packages that are required to run tests and should, therefore, be installed on the Sauce Labs VM. See Including Node Dependencies.
packages:
lodash: "4.17.20"
"@babel/preset-typescript": "7.12"
"@testcafe/react": "^5.0.1"
dependencies
| OPTIONAL | ARRAY |
Specifies any npm packages that are required to run tests and should, therefore, be included in the bundle.
Unlike packages
, which installs dependencies on the VM, the dependencies specified here have to be already installed in the local node_modules
folder. These dependencies, along with any related transitive dependencies, are then included in the bundle that is uploaded to Sauce Labs.
If you have already been including node_modules
in your bundle, then this feature will help you speed up your tests by reducing the amount of files in the bundle. A smaller bundle will upload and extract faster, which speeds up the setup on the VM, facilitating a faster test feedback cycle.
Take note that the syntax is different from packages
. It's a simple list of dependencies, without the need to specify the version.
npm:
dependencies:
- lodash
To use this feature, make sure that node_modules
is not ignored via .sauceignore
.
This feature is highly experimental.

| OPTIONAL | STRING |
When sharding is configured, saucectl automatically splits the tests (e.g., by spec or concurrency) so that they can easily run in parallel. For sharding by concurrency, saucectl splits test files into several groups (the number of groups is determined by the concurrency setting). Each group will then run as an individual job.
Selectable values: spec
to shard by spec file, concurrency
to shard by concurrency. Remove this field or leave it empty ""
for no sharding.
To split tests in the most efficient way possible, use:
spec
when the number of specs is less than the configured concurrency.concurrency
when the number of specs is larger than the configured concurrency.
