Espresso: [BUG]: Espresso Doesn't Match SVG Drawable When Many Characters

See: https://issuetracker.google.com/119052092

Hi there,

I'm using AS and Espresso to match a Vector drawable against the drawable on my imageView and after many attempts to solve an issue I'm inclined to believe there may be an issue with AS or Espresso itself instead. It seems some paths for the generated SVG don't work, usually the ones with more characters. When I comment those out then my code works fine.

I'm sending attached the image of the lines I need to comment to match the drawable. That's the SO link for the issue:

And this is one of my sample Vector Drawable:

  <!--android:pathData="M47.31,38.87h8a3.09,3.09 0,0 0,3.11 -2.81,3 3,0 0,0 -0.88,-2.36 3,3 0,0 0,-2.14 -0.89H30.84A1.06,1.06 0,0 1,30.09 31l6.07,-6.07a3.09,3.09 0,0 0,0.19 -4.21,3 3,0 0,0 -4.41,-0.13L18.19,34.33c-6.2,6.21 -6.43,16 1.43,20.65"-->
  <!--android:strokeWidth="1.97"-->

  <!--android:strokeLineCap="round"/>-->

  <!--android:pathData="M54.91,43.54s3.42,4 3.42,7.05a3.42,3.42 0,0 1,-6.84 0c0,-3 3.42,-7.05 3.42,-7.05"-->
  <!--android:strokeWidth="1.97"-->
  <!--android:fillColor="#00000000"-->
  <!--android:strokeColor="#89d3dd"-->
  <!--android:strokeLineCap="round"/>-->

  <!--android:pathData="M54.8,48.13a5.3,5.3 0,0 0,-0.52 2,1.79 1.79,0 0,0 0.79,1.5"-->
  <!--android:strokeWidth="1.97"-->
  <!--android:fillColor="#00000000"-->
  <!--android:strokeColor="#89d3dd"-->
  <!--android:strokeLineCap="round"/>-->

These being the lines I need to comment out:

  <!--android:pathData="M47.31,38.87h8a3.09,3.09 0,0 0,3.11 -2.81,3 3,0 0,0 -0.88,-2.36 3,3 0,0 0,-2.14 -0.89H30.84A1.06,1.06 0,0 1,30.09 31l6.07,-6.07a3.09,3.09 0,0 0,0.19 -4.21,3 3,0 0,0 -4.41,-0.13L18.19,34.33c-6.2,6.21 -6.43,16 1.43,20.65"-->

Thank you very much.

Beginne damit, das Beispiel-Vector-Drawable mit Espresso zu reproduzieren, und vergleiche das Rendering- und Matching-Verhalten mit aktivierten und deaktivierten drei auskommentierten Pfadelementen. Das Issue enthält weder eine Repository-Datei noch einen Test-Einstiegspunkt; als erledigt gilt, den Grund zu identifizieren, warum diese Pfade den Drawable-Abgleich verhindern, und einen reproduzierbaren Regressionstest oder eine dokumentierte Lösung hinzuzufügen.
