This assertion is used to check if the element described by the expression exists. The presence of the element, even empty, is enough to consider it a valid assertion.
|Mode||‘all’ or ‘one’||No|
|Level||‘error’ or ‘warning’||No|
|Stop test if fails||‘true’ or ‘false’||No|
Expression: It’s the path to the element we want to operate on (ex: payload.ProductID). See Expression for more details.
Mode: Specify if all the same elements in the payload should match the assertion (‘all’) or if only one element (‘one’) is enough.
Level: Specify if the assertion fails whether it should be considered an ‘error’ or just a ‘warning.’ A warning will not trigger alerts (such as email or text messages).
Modifier: The assertion is considered verified if it does not pass.
Stop test if fails: The test will be immediately stopped if the assertion fails.
