Test Suites & Reports

Running multiple tests

Maestro can run a suite of tests and generate a test report at the end.

To run a suite, point maestro test to a folder that contains the Flows

maestro test myFolderWithTests/

Maestro will run every flow from the directory excluding subfolders. The command will complete successfully if and only if all the Flows have been completed successfully.

Generating reports

To generate a report, add a --format parameter to a test command:

maestro test --format junit myFolderWithTests/

Or, if you are using Maestro Cloud:

maestro cloud --format junit myFolderWithTests/

Once execution completes, the report will be stored in a report.xml file in a JUnit-compatible format that is supported by most platforms.

Supported formats

  • junit - JUnit XML format

Additional options

  • --output {file} allows to override the report filename

Controlling what tests to include

There are multiple mechanisms to control what Flows to run when running a test suite.


Flow tags are covered extensively in the following section:


Inclusion Patterns

By default, when running a test suite, only Flows from the top level of a given directory will be executed. Consider the following folder structure:


When running a test or cloud command on a workspace folder, only flowA.yaml will be executed by default (though it is still able to refer to subFolder/flowB.yaml and subFolder/subSubFolder/flowC.yaml using runFlow command).

This behaviour can be customised by using inclusion patterns. To do that, update your config.yaml (create the file if missing) as follows:

  - "*"             # the default behaviour
  - "subFolder/*"

In such case, both flowA and flowB will be included in the test suite but not flowC.

Tests can also be included recursively:

  - "**"

In this example, all Flows A, B, and C will be included in the test suite.

Sequential execution

To run your Flows in a given order, you can add the following configuration to your config.yaml file:

# config.yaml
    continueOnFailure: false # default is true
        - flowA
        - flowB

This configuration describes to Maestro the order of the Flows you want to run. The list accepts either the Flow file names (without the .yaml extension) or the Flow name.

The continueOnFailure flag determines whether Maestro should proceed with the execution of subsequent Flows defined in the sequence if a previous one fails. As an example: if flowA fails and continueOnFailure is true, flowB will be executed. If the flag is false, flowB won't be executed. Note that Flows that are not defined in executionOrder will not be impacted and will always be run after the sequential Flows, irrespective of this Flow.

Note that your Flows should not depend on device state and should be treated as isolated, even though they run in sequence. A good rule of thumb is to ensure that each Flow can be run on a completely reset device.

Configuring part of the Flows to run sequentially

For instance, if you have three Flows, flowA, flowB, and flowC, but you want to run only flowA and flowB sequentially, don't add flowC and flowD to the list. Maestro will run these Flows in non-deterministic ordering after the Flow sequence has finished executing.

Deterministic ordering

Note that deterministic ordering has been deprecated in favour of sequential execution and will be removed in a future version.

This option is not supported for Maestro Cloud tests. All tests in a suite are going to be executed in parallel, regardless of this setting.

Normally, tests in a suite are executed in a non-deterministic order. In cases where a fixed order of execution is required, you can force your tests to run in alphabetical order. Update your config.yaml (or create the file if missing) to enable this behaviour:

  deterministicOrder: true
