Assert Contains

Legacy Documentation
You're viewing legacy documentation for API Fortress (deployed via an on-premises container). To view documentation for the new SaaS version of API Fortress — now known as Sauce Labs API Testing and Monitoring (with Sauce Connect tunnels) — see API Testing on the Sauce Labs Cloud.

This assertion is used to check if the element described by the expression contains a specific substring. For example, to test the word Uber is in Uber's product names (UberX, UberBlack, UberPool).

  • Expression: The path to the element we want to operate on (e.g., payload.ProductID). See Expression for more details.
  • Value: The value we want to compare the expression to.
  • Mode: Specify if all the same elements in the payload should match the assertion (‘all’) or if only one element (‘one’) is enough.
  • Level: Specifies, when the assertion fails, whether it should be considered an error or just a warning.
  • Modifier: The assertion is considered verified if it does not pass.
  • Execute if item exists: The assertion is evaluated only if the element exists. This is useful when the element does not always exist.
  • Stop test if fails: The test will be immediately stopped if the assertion fails.
  • Comment: Add comment messages in the form of a string data type.
note

A warning will not trigger alerts (such as email or text messages).
