[@angular/build:unit-test][vitest] Vitest snapshot testing #30439

Closed
@timdeschryver

Description

Command

test

Description

Snapshot testing with Vitest is currently not supported.
The inline snapshots throw an error, and the file snapshots are stored in the dist folder which defeats the purpose of snapshot testing since these are not commited.

As an example see https://github.com/timdeschryver/VitestAngular/blob/main/src/app/app.spec.ts#L16.

Running the tests throws the following error:

TypeError: Cannot read properties of null (reading 'length')
