Use a file as input to unit tests

[eitland]

I think I have seen an elegant way to use a file as input for a unit test in apache camel but my google skills are failing me.

What I want is instead of:

String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" +
    <snip>...long real life xml that quickly fills up test files.</snip>";
template.sendBody("direct:create", xml);

What I think I have seen is something like:

template.sendBody("direct:create", someCamelMetod("/src/data/someXmlFile.xml"));

Anybody knows where/if this is documented?

May be context.getTypeConverter().convertTo(String.class,
this.getClass().getResourceAsStream("/src/data/someXmlFile.xml"));

Apache commons-io provides also some useful methods for this [1].

Best,
Christian

Hi Christian and thanks!

I ended up creating a simple helper function: private void readFile(String fileName) throws ...

Still I think I have seen an even more elegant solution somewhere.

The question is also cross posted to StackOverflow (http://stackoverflow.com/questions/13209889/use-a-file-as-input-to-unit-tests) and I'm be happy to hand out some upvotes : )

Hi

Do you mean:

template.sendBody("direct:create", context.getTypeConverter().convertTo(String.class, new File("src/data/someXmlFile.xml")));

Ah just spotted that Christian has already suggested the same approach so
please ignore my answer.

You may also just send the java.io.File as body. As often the type
conversion will kick in and load the content using a FileInputStream
out of the box, when needed. Though you can also as Babak has shown
cover the file to a String beforehand.
