There was no easy way to automatically test the end-to-end functionality
of commands, flags, environment variables etc.
The need for end-to-end testing was highlighted by the issues fixed
in #5341. There was no automated test to continually verify current
behaviour, nor a framework to quickly test the correctness of the fixes.
This change adds an end-to-end testing framework in the cmdtest folder.
It has some simple examples in func TestCmdTest in cmdtest_test.go. The
tests should be readable by anybody familiar with rclone and look like
this:
// Test the rclone version command with debug logging (-vv)
out, err = rclone("version", "-vv")
if assert.NoError(t, err) {
assert.Contains(t, out, "rclone v")
assert.Contains(t, out, "os/version:")
assert.Contains(t, out, " DEBUG : ")
}
The end-to-end tests are executed just like the Go unit tests, that is:
go test ./cmdtest -v
The change also contains a thorough test of environment variables in
environment_test.go.
Thanks to @ncw for encouragement and introduction to the TestMain trick.
Some environment variables didn’t behave like their corresponding
command line flags. The affected flags were --stats, --log-level,
--separator, --multi-tread-streams, --rc-addr, --rc-user and --rc-pass.
Example:
RCLONE_STATS='10s'
rclone check remote: remote: --progress
# Expected: rclone check remote: remote: --progress –-stats=10s
# Actual: rclone check remote: remote: --progress
Remote specific options set by environment variables was overruled by
less specific backend options set by environment variables. Example:
RCLONE_DRIVE_USE_TRASH='false'
RCLONE_CONFIG_MYDRIVE_USE_TRASH='true'
rclone deletefile myDrive:my-test-file
# Expected: my-test-file is recoverable in the trash folder
# Actual: my-test-file is permanently deleted (not recoverable)
Backend specific options set by environment variables was overruled by
general backend options set by environment variables. Example:
RCLONE_SKIP_LINKS='true'
RCLONE_LOCAL_SKIP_LINKS='false'
rclone lsd local:
# Expected result: Warnings when symlinks are skipped
# Actual result: No warnings when symlinks are skipped
# That is RCLONE_SKIP_LINKS takes precedence
The above issues have been fixed.
The debug logging (-vv) has been enhanced to show when flags are set by
environment variables.
The documentation has been enhanced with details on the precedence of
configuration options.
See pull request #5341 for more information.
Improved/added steps to:
* Install Git with basic setup
* Use both SSH and HTTPS for the git origin
* Install Go and verify the GOPATH
* Update the forked master
* Find a popular editor for Go
OneDrive randomly returns the error message: "InvalidAuthenticationToken: Unable to initialize RPS". These unexpected errors typically caused the entire rclone command to fail.
This work around recognizes these errors and marks them for a low level retry, that mostly succeeds. This will make rclone commands complete without being noticeable affected.
Fixes: #5270
