Upgrading

This section will cover breaking changes between major versions and other related information to ease upgrading to the latest version.

Migrating from v1.x to v2.x

Configuration change

In v1 the extension only had a single configuration option, which was base_uri. This is still the only option in v2, but it has been added to an apiClient key.

v1 behat.yml

default:
    suites:
        default:
            # ...

    extensions:
        Imbo\BehatApiExtension:
            base_uri: http://localhost:8080

v2 behat.yml

default:
    suites:
        default:
            # ...

    extensions:
        Imbo\BehatApiExtension:
            apiClient:
                base_uri: http://localhost:8080

Renamed public methods

The following public methods in the Imbo\BehatApiExtension\Context\ApiContext class have been renamed:

v1 method name v2 method name
givenIAttachAFileToTheRequest addMultipartFileToRequest
givenIAuthenticateAs setBasicAuth
givenTheRequestHeaderIs addRequestHeader
giventhefollowingformparametersareset setRequestFormParams
givenTheRequestBodyIs setRequestBody
givenTheRequestBodyContains setRequestBodyToFileResource
whenIRequestPath requestPath
thenTheResponseCodeIs assertResponseCodeIs
thenTheResponseCodeIsNot assertResponseCodeIsNot
thenTheResponseReasonPhraseIs assertResponseReasonPhraseIs
thenTheResponseStatusLineIs assertResponseStatusLineIs
thenTheResponseIs assertResponseIs
thenTheResponseIsNot assertResponseIsNot
thenTheResponseHeaderExists assertResponseHeaderExists
thenTheResponseHeaderDoesNotExist assertResponseHeaderDoesNotExists
thenTheResponseHeaderIs assertResponseHeaderIs
thenTheResponseHeaderMatches assertResponseHeaderMatches
thenTheResponseBodyIsAnEmptyObject assertResponseBodyIsAnEmptyJsonObject
thenTheResponseBodyIsAnEmptyArray assertResponseBodyIsAnEmptyJsonArray
thenTheResponseBodyIsAnArrayOfLength assertResponseBodyJsonArrayLength
thenTheResponseBodyIsAnArrayWithALengthOfAtLeast assertResponseBodyJsonArrayMinLength
thenTheResponseBodyIsAnArrayWithALengthOfAtMost assertResponseBodyJsonArrayMaxLength
thenTheResponseBodyIs assertResponseBodyIs
thenTheResponseBodyMatches assertResponseBodyMatches
thenTheResponseBodyContains assertResponseBodyContainsJson

Some methods have also been removed (as the result of removed steps):

  • whenIRequestPathWithBody
  • whenIRequestPathWithJsonBody
  • whenISendFile

Updated steps

v1 contained several When steps that could configure the request as well as sending it, in the same step. These steps has been removed in v2.0.0, and the extension now requires you to configure all aspects of the request using the Given steps prior to issuing one of the few When steps.

Given the request body is :string

This step now uses a <PyStringNode> instead of a regular string:

v1

Given the request body is "some data"

v2

Given the request body is:
    """
    some data
    """

When I request :path using HTTP :method with body: <PyStringNode>

The body needs to be set using a Given step and not in the When step:

v1

When I request "/some/path" using HTTP POST with body:
    """
    {"some":"data"}
    """

v2

Given the request body is:
    """
    {"some":"data"}
    """
When I request "/some/path" using HTTP POST

When I request :path using HTTP :method with JSON body: <PyStringNode>

The Content-Type header and body needs to be set using Given steps:

v1

When I request "/some/path" using HTTP POST with JSON body:
    """
    {"some":"data"}
    """

v2

Given the request body is:
    """
    {"some":"data"}
    """
And the "Content-Type" request header is "application/json"
When I request "/some/path" using HTTP POST

When I send :filePath (as :mimeType) to :path using HTTP :method

These steps must be replaced with the following:

v1

When I send "/some/file.jpg" to "/some/endpoint" using HTTP POST
When I send "/some/file" as "application/json" to "/some/endpoint" using HTTP POST

v2

Given the request body contains "/some/file.jpg"
When I request "/some/endpoint" using HTTP POST
Given the request body contains "/some/file"
And the "Content-Type" request header is "application/json"
When I request "/some/endpoint" using HTTP POST

The first form in the old and new versions will guess the mime type of the file and set the Content-Type request header accordingly.

Then the response body is an empty object

Slight change that adds “JSON” in the step text for clarification:

v1

Then the response body is an empty object

v2

Then the response body is an empty JSON object

Then the response body is an empty array

Slight change that adds “JSON” in the step text for clarification:

v1

Then the response body is an empty array

v2

Then the response body is an empty JSON array

Then the response body is an array of length :length

Slight change that adds “JSON” in the step text for clarification:

v1

Then the response body is an array of length 5

v2

Then the response body is a JSON array of length 5

Then the response body is an array with a length of at least :length

Slight change that adds “JSON” in the step text for clarification:

v1

Then the response body is an array with a length of at least 5

v2

Then the response body is a JSON array with a length of at least 5

Then the response body is an array with a length of at most :length

Slight change that adds “JSON” in the step text for clarification:

v1

Then the response body is an array with a length of at most 5

v2

Then the response body is a JSON array with a length of at most 5

Then the response body contains: <PyStringNode>

Slight change that adds “JSON” in the step text for clarification:

v1

Then the response body contains:
    """
    {"some": "value"}
    """

v2

Then the response body contains JSON:
    """
    {"some": "value"}
    """

Functions names for the JSON matcher

When recursively checking a JSON response body, some custom functions exist that is represented as the value in a key / value pair. Below is a table of all available functions in v1 along with the updated names used in v2:

v1 function v2 function
@length(num) @arrayLength(num)
@atLeast(num) @arrayMinLength(num)
@atMost(num) @arrayMaxLength(num)
<re>/pattern/</re> @regExp(/pattern/)

v2 have also added more such functions, refer to the Custom matcher functions and targeting section for a complete list.

Exceptions

The extension will from v2 on throw native PHP exceptions or namespaced exceptions (like for instance Imbo\BehatApiExtension\Exception\AssertionException). In v1 exceptions could come directly from beberlei/assert, which is the assertion library used in the extension. The fact that the extension uses this library is an implementation detail, and it should be possible to switch out this library without making any changes to the public API of the extension.

If versions after v2 throws other exceptions it should be classified as a bug and fixed accordingly.
