# For this test to pass without actual Tailscale, the action must gracefully handle
# the SSH connection attempt. The mock SSH server will still require some form of auth.
# The action should attempt to connect, and our mock docker should log calls.
# We need to ensure the SSH setup part of the action *doesn't* try to write id_rsa if tailscale_ssh is true.
# This test primarily verifies that the action *would* skip its own keygen if Tailscale is true.
# Actual Tailscale functionality cannot be tested here easily.

# implying that the SSH setup part didn't fatally error due to missing keys.

# The env blocks are evaluated early.
# A better way: output keys to GITHUB_ENV for subsequent steps in *this job*.

echo "TEST_SSH_PUBLIC_KEY_CONTENT=$(cat test_ssh_key.pub)" >> $GITHUB_ENV
echo "SSH keys set to GITHUB_ENV for subsequent steps in this job."
# This final step is to ensure the keys are correctly populated in the test steps
# The above 'Update SSH keys' step needs to run *before* any test case that uses them.
# The structure above is problematic because env blocks are processed early.
# Corrected approach: Generate keys, then have all test steps use them from files or GITHUB_ENV.
# Let's restructure:
# 1. Job to generate keys and pass them as outputs.
# 2. Subsequent job that uses these keys.
# OR, for simplicity in a single job:
# Generate keys -> set to GITHUB_ENV -> all test steps use `env.TEST_SSH_PRIVATE_KEY_CONTENT`
# The current structure has a flaw: the env: blocks in each 'uses: ./' step are static.
# They won't pick up keys generated within the same job in a prior step directly like that.
# I need to adjust how the keys are passed to the action.
# The easiest way is to read them from files that the 'Generate SSH keys' step creates.
# The action itself would then receive the *content* of these files.
# Let's refine the key generation and usage.
# The `env:` block for each `uses: ./` should be removed, and the `with:` block should read from files.
# Example: ssh_private_key: ${{ steps.generate_keys.outputs.private_key }}
# I will simplify the key injection for now by directly using cat in the `with` block.
# This is not ideal for multi-line private keys in YAML but works for demonstration.
# A better approach is to use `steps.<id>.outputs.<name>` after the key generation step.
# I will make this correction in the next iteration if this proves clunky.
# For now, the `REPLACE_WITH_GENERATED_PRIVATE_KEY` is a placeholder.
# The `Update SSH keys in workflow file (TEMPORARY HACK)` step is not effective as placed.
# I will remove it and assume the keys need to be manually inserted or a better mechanism used.
# For now, to make progress, I will assume the keys are available as secrets or manually placed for a first pass.
# The key generation part is more for setting up the *service container*.
# The action inputs `ssh_private_key` and `ssh_public_key` would typically come from secrets.
# Let's assume for the mock tests, we will use fixed dummy keys that are part of the repo,
# or I will use the generated ones and adjust the workflow to correctly pass them.
# Correcting the key passing strategy:
# The 'Generate SSH keys' step will output the key contents.
# Subsequent steps will use these outputs.
# I need to give the key generation step an ID.
# This is a significant change to the test structure.
# I will proceed with creating this file, and then refine the key passing in the next tool call if needed.
# The current `REPLACE_WITH_GENERATED_PRIVATE_KEY` will cause tests to fail until fixed.
# I will make a note to fix this specifically.
# The current version of the workflow has placeholders for keys.
# I will first write this file and then refine the key management.
