Json Assertion Post Processors lets you check at runtime the HTTP responses satisfy conditions, e.g.:
- The Json body contains a particular path,
- A node of the Json response has a particular value.
Assertions can be graphed in bench reports.
You can use our Json path selector to configure your expression from a node in the Json tree:
Select Yes to reverse the search. This can be useful to check you do not have an error message.
Assert value allows you to also control the value of the node highlighted in the Json path field. This way you can control, not only that it exists but that it has the value you are looking for.
Use Expect null? if the value is expected to be empty. Use Is regex? to use a regex expression in the value.
Opening the debug panel allows you to quickly see the result of your assertion. Make sure to check it every time you make a significant change:
