Create Expectation

When you create an expectation, you can define a name of your choice. It is advisable to assign the name in a meaningful way, so that the assignment of the exposure in the job definition is as easy as possible.

The following expectations can be defined using a JSON string:

Typ Zweck Definition Erklärung

Typ	Zweck	Definition	Erklärung
`StringCountExpectation`	Check the server response for the presence of a certain number of strings	`value` and `count`	`value` defines the text value to be searched for. The frequency is set with the `count` attribute.
`RegularExpressionExpectation`	Verification of the server response by regular expressions	Single values in the JSON array	Each value is considered a regular expression and checked (see `matchAll` `true` or `false`)
`StringContainsExpectation`	Check the server response for the presence of strings	Single values in the JSON array	Each value is checked for presence in the server response (see `matchAll` `true` or `false`)
`HttpHeaderAvailableExpectation`	Check the server response for the presence of HTTP Headers	Single values in the JSON array	Each value is checked for presence in the server response (see `matchAll` `true` or `false`)
`HttpHeaderAndValueExpectation`	Does a comparison of HTTP Header values for both textual or numeric compare	Three values: HTTP Header name, comparison operator and comparison value	Combination of Header, comparison operator and value will be checked with the server response’s HTTP Header. Textual comparison: eq and like Numeric comparison: =, <, <=, >, >=

StringCountExpectation

Check the server response for the presence of a certain number of strings

value and count

value defines the text value to be searched for. The frequency is set with the count attribute.

RegularExpressionExpectation

Verification of the server response by regular expressions

Single values in the JSON array

Each value is considered a regular expression and checked (see matchAll true or false)

StringContainsExpectation

Check the server response for the presence of strings

Single values in the JSON array

Each value is checked for presence in the server response (see matchAll true or false)

HttpHeaderAvailableExpectation

Check the server response for the presence of HTTP Headers

Single values in the JSON array

Each value is checked for presence in the server response (see matchAll true or false)

HttpHeaderAndValueExpectation

Does a comparison of HTTP Header values for both textual or numeric compare

Three values: HTTP Header name, comparison operator and comparison value

Combination of Header, comparison operator and value will be checked with the server response’s HTTP Header.

Textual comparison: eq and like

Numeric comparison: =, <, <=, >, >=

In the content field of the expectation, a type is defined via the JSON notation, which controls the evaluation of the server response. In the content section, a JSON array can always be used to define several individual conditions (see table above and the examples on the website).

The matchAll switch can be used to decide whether all conditions must be met in order for the service to be evaluated positively or for the fulfillment of a condition to be sufficient.

Test Expectations

In the lower input field you can simulate server responses and test them against the current definition of the expectation. In the above example, the expectation would not be fulfilled because matchAll is set to true and the condition text2 occurs once only with the example answer does not apply.

Testing HTTP Header related expectations can be done by adding HTTP Header line by line to the content field: <HTTP-Header>: <HTTP-HEADER-VALUE>
