title: “Downloading Isolates” linkTitle: “Downloading Isolates”

The intermediate and final build products from running tests are all stored in Isolate, and can be downloaded to the desktop for inspection and debugging.

First install the client:

 git clone https://github.com/luci/client-py.git

Add the checkout location to your $PATH.

To download the isolated files for a test first visit the build status page and find the “isolated output” link:

Follow that link to find the hash of the isolated outputs:

Then run isolateserver.py with --isolated set to that hash:

$ isolateserver.py \
  download \
  --isolate-server=https://isolateserver.appspot.com \
  --isolated=5b85b7c382ee2a34530e33c7db20a07515ff9481 \
