Similar to the profile image, we can also send the document part of the whole request payload: bodyBuilder.

The real kicker here is setting up the Header part as that is what’s used by the webtestclient internals (specifically the Synchronoss-nio library which webflux uses internally) to determine the type of form data being sent and how to process it.Īlso, note that the real file name that will get uploaded in the web server receiving the request is the profile-image.jpg filename that gets sent as part of the headers. To explain a bit about what’s going on there, we’re simply telling the body builder to upload an image found in src/test/resources folder with the name test-image.jpg as the profile image part of this body. header ( "Content-Disposition", "form-data name=profileImage filename=profile-image.jpg" ) part ( "profileImage", ClassPathResource ( "test-image.jpg" ). To send the first part, the profile image we can set it up as: val bodyBuilder = MultipartBodyBuilder ( )īodyBuilder.

Profile Image ( api label: profileImage).To aid with our example, lets imagine the form is a profile setup for an document share service and takes the following input: Let’s suppose that we’re trying to send the request to fill a form api that accepts a document (image, text, plain binary etc.) and some textual data.

Recently, while integration testing an application that accepted data as multipart/form-data I had to figure out how to test the data effectively using the webtestclient and personally found the lack of comprehensive resources on the internet lacking, so I wrote this blogpost to share my own learnings. WebTestClient is a reactive testing high level http client with fluent assertions, packaged in spring web flux. But essentially reactive programming involves a model of creating, requesting and manipulating data in a controllable (from a consumers perspective) and non-blocking manner. For the past year or so, I have been working extensively with spring, especially spring webflux building scalable reactive micro services for our customers.Ĭoming from spring MVC, learning webflux and getting used to reactive programming in general has been a great and worthy learning experience and I highly suggest going through the references section if you haven’t heard of reactive programming and/or have been thinking about giving it a go and don’t know where to start.
