Summary
When using snapshot testing, Angular will generate
<div id="root{n}">
root tag every time callTestBed.createComponent
; this attribute will cause the snapshot not to be stable and should be removed when serializing content.Test plan
I have updated the testing snapshot content, fixed the code, and the snapshot testing passed.
Does this PR introduce a breaking change?
All old snapshots containing
<div id="root{n}">
will cause failure.So developers have to update the new snapshot manually after the upgrade.
