These tests are specifically for the command-line interface and cover: - resume/soft-reset/connect/disconnect - mount - fs cp,touch,mkdir,cat,sha256sum,rm,rmdir - eval/exec/run This work was funded through GitHub Sponsors.

# Tests for mpremote
2+
3+
This directory contains a set of tests for `mpremote`.
4+
5+
Requirements:
6+
- A device running MicroPython connected to a serial port on the host.
7+
- Python 3.x, `bash` and various Unix tools such as `find`, `mktemp`, `sed`, `sort`, `tr`.
8+
9+
To run the tests do:
10+
11+
$ ./run-mpremote-tests.sh
12+
13+
Each test should print "OK" if it passed. Otherwise it will print "CRASH", or "FAIL"
14+
and a diff of the expected and actual test output.
