Retry Utilities

Retry helper functions for libtmux test utilities. These utilities help manage testing operations that may require multiple attempts before succeeding.

Basic Retry Functionality

Retry helpers for libtmux and downstream libtmux libraries.

libtmux.test.retry.retry_until(fun, seconds=8, *, interval=0.05, raises=True)

Retry a function until a condition meets or the specified time passes.

Return type:

bool

Parameters:

• fun (callable) – A function that will be called repeatedly until it returns True or the specified time passes.

• seconds (float) – Seconds to retry. Defaults to 8, which is configurable via RETRY_TIMEOUT_SECONDS environment variables.

• interval (float) – Time in seconds to wait between calls. Defaults to 0.05 and is configurable via RETRY_INTERVAL_SECONDS environment variable.

• raises (bool) – Whether or not to raise an exception on timeout. Defaults to True.

Examples

>>> def fn():
...     p = session.active_window.active_pane
...     return p.pane_current_path is not None

>>> retry_until(fn)
True

In pytest:

>>> assert retry_until(fn, raises=False)
