4.4Headers
Type: header.<Name>, such as header.Content-Type. Checks: the value of one response header. A header is a named line of extra information sent with the response. In the dashboard, choose header and type the name in the header name box.
- Upper and lower case in the header name do not matter. In the value, they do.
- A missing header reads as empty text.
- If you type a value but no name, the dashboard shows Enter the header name.
Operators: eq, neq, contains, matches. Use gt and lt for headers that hold a number, such as Content-Length or Age.
| Type | Operator | Value | What it means |
|---|---|---|---|
header.Content-Type | contains | application/json | The API responds with JSON. |
header.Cache-Control | contains | max-age | Browsers may store the page for a while. |
header.X-Version | matches | ^2\. | A custom header reports version 2. |
When it fails: assertion header.Content-Type contains "application/json": got "text/html". Long values are cut to 40 characters.
