Use Prerequisites and Dependencies

Use prerequisite and dependent tests to share setup without making every scenario long and repetitive.

Some tests need another flow to happen first. TestVibe can model that relationship with prerequisites or dependent tests.

Use dependencies when one test creates or prepares the state another test needs.

When To Use A Prerequisite

Use a prerequisite when:

Situation	Example
A setup flow is reused	Sign in before account settings tests.
One feature creates required data	Create a customer before editing customer details.
A path is too long to repeat	Complete onboarding before testing dashboard behavior.
A setup step should be reviewed separately	Create invoice before testing invoice download.

Do not use dependencies for every small step. If setup is short and only belongs to one scenario, keep it in the scenario or Background.

Example

Prerequisite feature:

Feature: Customer creation

  Scenario: Admin creates an active customer
    Given the admin is on the customers page
    When the admin creates a customer named "Acme QA"
    Then the customer record should be visible

Dependent feature:

Feature: Customer billing

  Scenario: Admin updates billing contact
    Given the "Acme QA" customer exists
    When the admin updates the billing contact email
    Then the new billing contact should be saved

The dependent feature can refer to the setup expectation without repeating every creation step.

How Dependencies Affect Maintenance

When you change a prerequisite, review the tests that depend on it.

Change	What to check
Rename fields or buttons	Dependent generated tests may need regeneration.
Change created data	Dependent tests may need updated expected values.
Move the setup flow	Dependent features may need clearer starting context.
Delete the prerequisite	Dependent tests may no longer be runnable.

Keep Dependencies Understandable

Good dependency chains are short and intentional.

Do:

• use one setup feature for a clear purpose

• describe the state the dependent test expects

• keep prerequisite names specific

• regenerate dependent tests after meaningful setup changes

Avoid:

• long chains of dependencies

• hidden setup that is not mentioned in the dependent scenario

• relying on fragile data created by another team's manual process

Alternatives

Need	Better option
Shared setup for every scenario in one feature	Use Background.
One-time project or environment setup	Use project settings, secrets, or test data setup outside the scenario.
A short setup action used once	Keep it inside the scenario.
A repeated multi-step setup journey	Use a prerequisite or dependent test.

After defining dependencies, generate or regenerate the affected tests. See Generate Playwright code.
