Technically it wasn't "all was good" since it's broken if you run from a clean state, so that's why it's gone as par #6327, #6332 https://stackblitz.com/edit/vitest-dev-vitest-bdoulsxd?file=test%2Fbasic.test.ts function myTest() {
expect(1 + 1).toMatchInlineSnapshot(`2``2`);
}For this reproduction,

Hi Hiroshima, you’ve said “

clean state,
”
I understand that you had a bug with the generation and injection of
strings when you ran it in a clean test but I feel that the core value of
this method is to match inline string (even if I type it) breaking the
entire functionality of this use case only for a bug in a utility that
helps it happen is wrong in my opinion.

function myTest() {
expect(1 + 1).toMatchInlineSnapshot(`2``2`);}
For this reproduction, expect(1 + 1).toEqual(2) is probably the only
choice.
I have a shared test.ts file that is used by multiple test files that are
calling it and it uses toMatchInlineSnapshot.
Actually different test files calling toMatchInlineSnapshot might be a
workaround though

I roger what @noam-honig wrote. If I understand correctly, the root of this was: test("snap", () => {
for (const str of ["foo", "bar"]) {
expect(str).toMatchInlineSnapshot();
// transforms to expect(str).toMatchInlineSnapshot(`"foo"``"bar"`);
}
});Isn't it more a test("snap", () => {
for (const str of ["foo", "bar"]) {
expect(str).toMatchInlineSnapshot();
// transforms to expect(str).toMatchInlineSnapshot(`"foo"`);
// and fail the second expect
}
});Or maybe having a waring only at the generation of the transform from a cleanstate is sufficient? |
Describe the bug
I have a shared test.ts file that is used by multiple test files that are calling it and it uses
toMatchInlineSnapshot.It's a set of standard tests for a database that are executed for each database adapter implementation that I have.
All was great and worked in version 2.0.5. As soon as I updated to version 2.1.9 I started getting the error:
Error: toMatchInlineSnapshot cannot be called multiple times at the same location.
It is the same line of code of test that is executed several times wih multiple test files.
How can I fix rhat to work again?
