A simple testing framework |

To run the tests, do: |
|
4 |
|
|
5 |
cd tests/ |
|
6 |
./run-tests |
|
7 |
|
331
|

This finds all scripts in the test directory named test-* and executes |
|
9 |
them. The scripts can be either shell scripts or Python. Each test is |
|
10 |
run in a temporary directory that is removed when the test is complete. |
|
11 |
|
|
12 |
A test-<x> succeeds if the script returns success and its output |
|
13 |
matches test-<x>.out. If the new output doesn't match, it is stored in |
|
14 |
test-<x>.err. |

There are some tricky points here that you should be aware of when |
|
17 |
writing tests: |
|
18 |
|
|
19 |
- hg commit and hg up -m want user interaction |
|
20 |
|
|
21 |
for commit use -t "text" |
|
22 |
for hg up -m, set HGMERGE to something noninteractive (like true or merge) |
|
23 |
|
|
24 |
- changeset hashes will change based on user and date which make |
|
25 |
things like hg history output change |
|
26 |
|
|
27 |
use commit -t "test" -u test -d "0 0" |
|
28 |
|
|
29 |
- diff will show the current time |
|
30 |
|
|
31 |
use hg diff | sed "s/\(\(---\|+++\).*\)\t.*/\1/" to strip dates |
|
32 |
|
332
|
33 |
- set -x and pipelines don't generate stable output |
|
34 |
|
|
35 |
turn off set -x or break pipelines into pieces |
|
