mockMvc, get content from json file in SpringBoot

Question

I have a springBoot 2.1.9.RELEASE application that uses MockMvc.

I would like to know if there is a way to get the content of the body from a file

mockMvc.perform(post("/hostel")
    .content(withBodyFile("hostel.json"))

like we can do with

com.github.tomakehurst.wiremock.client.ResponseDefinitionBuilder (withBodyFile)

You could use something like:

@SneakyThrows
private byte[] fromFile(String path) {
    return new ClassPathResource(path).getInputStream().readAllBytes();
}

And then:

.content(fromFile("payload.json")))

Just bear in mind that the payload.json file must be under the src/test/resources folder.

Why isn't there any built-in way to do it? Is this so uncommon? It feels weird to me, looks like I'm doing something wrong

MockMvc's content can only be a byte[]. So, you can have your code read body from a file like

public byte[] bytesFromPath(final String path) throws IOException {

    return Files.readAllBytes(Paths.get(path));
}

.content(bytesFromPath(new ClassPathResource("file-name").getPath()));
