Applications are used to organize functionality, tests, and results into sets that are relevant to your organization. Many people choose to define one application for each unique product that they offer to their customers, while others choose to define applications at a more granular level. The former approach is more common with products that are supported by a single, relatively small development team, whereas the latter is more common with more feature-rich products that may be supported by multiple development teams.


An assertion is a statement about your application that you would like mabl to confirm is true when running a test. For example, when using the browser-based trainer, you might assert that a text field should have a certain value at a particular point in a test run.


Credentials provide mabl with authentication information for the purpose of executing a test. Today, mabl supports one type of credentials (username/password).


A deployment is an instance of an application running in an environment.


An environment is a resource to which mabl connects in order to execute a test. To illustrate, an application might have two environments; one for development, which is accessible via, and one for production, which is accessible via


A journey is the set of instructions that mabl must execute in order to verify that your application is functioning as expected. Instructions could include visiting a particular URL, clicking on a given field in a form, entering text, clicking on a button, verifying that a field has a certain value, verifying that an object loads, and more.


A plan specifies how mabl should test a journey. It tells mabl which application to test, which credentials to use (if applicable), which journeys to test, which environments to test against, and when the tests should be executed.


Workspaces are used to group applications, environments, credentials, journeys, plans, etc. into a set for the purpose of providing appropriate visibility and access control. A workspace is the broadest grouping within the mabl application. Users can belong to one or more workspaces.
