Why is test_inline! macro trying to read a file

[ptazithos]

I guess the test_inline! macro is supposed to compare an inline input with an inline output. However the actual implementation compares an inline input with file content.

Given the swc plugin template, there is a test at the bottom of lib.rs

test_inline!(
    Default::default(),
    |_| as_folder(TransformVisitor),
    boo,
    // Input codes
    r#"foo === bar;"#,
    // Output codes after transformed with plugin
    r#"foo == bar;"#
);

The test_line! macro invokes the function test_inline_input_output.

swc/crates/swc_ecma_transforms_testing/src/lib.rs

Lines 461 to 477 in fd7cf4c

	#[macro_export]
	macro_rules! test_inline {
	(ignore, $syntax:expr, $tr:expr, $test_name:ident, $input:expr, $output:expr) => {
	#[test]
	#[ignore]
	fn $test_name() {
	$crate::test_inline_input_output($syntax, $tr, $input, $output)
	}
	};
	($syntax:expr, $tr:expr, $test_name:ident, $input:expr, $output:expr) => {
	#[test]
	fn $test_name() {
	$crate::test_inline_input_output($syntax, $tr, $input, $output)
	}
	};
	}

then the function read_to_string inside test_inline_input_output takes the output string r#"foo == bar;"# as a file path to read a local file.

swc/crates/swc_ecma_transforms_testing/src/lib.rs

Line 364 in fd7cf4c

let expected = read_to_string(output);

It looks like my mistake. I'll fix it soon
