What is wexpect?

Wexpect is a Python module for spawning child applications and controlling them automatically. Wexpect can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup scripts for duplicating software package installations on different servers. It can be used for automated software testing. Wexpect is in the spirit of Don Libes' Expect, but Wexpect is pure Python. Other Expect-like modules for Python require TCL and Expect or require C extensions to be compiled. Wexpect does not use C, Expect, or TCL extensions.

Original Pexpect should work on any platform that supports the standard Python pty module. While Wexpect works on Windows platforms. The Wexpect interface focuses on ease of use so that simple tasks are easy.


Thanks for any contributing!


To run test, enter into the folder of the wexpect's repo then:

python -m unittest


The deployment itself is automated and done by appveyor. See after_test section in appveyor.yml for more details.

The wexpect uses pbr for managing releasing procedures. The versioning is handled by the pbr. The "master-version" is the git tag. Pbr derives the package version from the git tags.
