TLDR; Some tips for seeing traffic when using RestAssured.
RestAssured.filters( new RequestLoggingFilter(), new ResponseLoggingFilter());
When the above code is used then you will see logging messages to the console which show you the basic requests and responses that your messages send out.
Log to File
The Filters above can be instantiated with a
PrintStream to write to files.
RestAssured.filters(new RequestLoggingFilter(printToFile), new ResponseLoggingFilter(printToFile));
And here is a contextual example showing creating the file, the
FileOutputStream and the
// create a file in the project dir // named using current time in milliseconds final String currentDir = System.getProperty("user.dir"); File outputFile = new File(currentDir, "restassured" + System.currentTimeMillis()+".log"); System.out.println("log to file:" + outputFile.getAbsolutePath().toString());
Then, using the file to write.
FileOutputStream fileOutput = new FileOutputStream(outputFile); PrintStream printToFile = new PrintStream(fileOutput); // configuring RestAssured to use the file RestAssured.filters(new RequestLoggingFilter(printToFile), new ResponseLoggingFilter(printToFile));
I have found the logging approach useful for simple debugging and for seeing the output.
But when I really want to have a detailed look at the traffic, I prefer to go through a proxy.
RestAssured has a very simple proxy configuration.
I find I need to set the relaxed HTTPS validation when going through a proxy.
You can find the example code for this in:
