Macro get_test_bin 

macro_rules! get_test_bin {
    ($x:expr) => { ... };
}

Returns the crate’s binary as a Command that can be used for integration tests.

Arguments

• bin_name - The name of the binary you want to test. It must be a string literal.

Remarks

It will fail to compile if the bin_name is incorrect. The bin_name is used for creating an environment variable.

If you want to not use a string literal every time then you can define a macro that returns a string literal:

macro_rules! my_cli_app {
   () => ( "my_cli_app" )
}

And then use my_cli_app!() as the argument.
