Crate assert_call

A tool for testing that ensures code parts are called as expected.

By creating an instance of CallRecorder, it starts recording the calls to call, and then CallRecorder::verify verifies that the calls to call are as expected.

The pattern of expected calls specified in CallRecorder::verify uses Call.

Examples

use assert_call::{call, CallRecorder};

let mut c = CallRecorder::new();

call!("1");
call!("2");

c.verify(["1", "3"]);

The above code panics and outputs the following message because the call to call macro is different from what is specified in CallRecorder::verify.

actual calls :
  1
* 2
  (end)

mismatch call
src\lib.rs:10
actual : 2
expect : 3

Backtrace support

If backtrace capture is enabled at Backtrace::capture, CallRecorder::verify outputs detailed information including the backtrace for each call! call.
