Running the tests
|

~~~~~~~~~~~~~~~~~
|
||||
|
||||
The tests are run by calling `runtest` in the test directory:

|
||||
Fixing a completion test
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
Let's consider this real-life example where an ssh completion bug is fixed. First you're triggered by unsuccessful tests:
|
||||
|
||||
----------------------------------
|
||||
$ ./runCompletion
|
||||
...
|
||||
=== completion Summary ===
|
||||
|
||||
# of expected passes 283
|
||||
# of unexpected failures 8
|
||||
# of unresolved testcases 2
|
||||
# of unsupported tests 47
|
||||
----------------------------------
|
||||
|
||||
Take a look in `log/completion.log` to find out which specific command is failing.
|
||||
|
||||
-----------------------
|
||||
$ vi log/completion.log
|
||||
-----------------------
|
||||
|
||||
Search for `UNRESOLVED` or `FAIL`. From there scroll up to see which `.exp` test is failing:
|
||||
|
||||
---------------------------------------------------------
|
||||
/@Running ./completion/ssh.exp ...
|
||||
...
|
||||
UNRESOLVED: Tab should complete ssh known-hosts at prompt
|
||||
---------------------------------------------------------
|
||||
|
||||
In this case it appears `ssh.exp` is causing the problem. Isolate the `ssh` tests by specifying just `ssh.exp` to run. Furthermore add the `--debug` flag, so output gets logged in `dbg.log`:
|
||||
|
||||
----------------------------------
|
||||
$ ./runCompletion ssh.exp --debug
|
||||
...
|
||||
=== completion Summary ===
|
||||
|
||||
# of expected passes 1
|
||||
# of unresolved testcases 1
|
||||
----------------------------------
|
||||
|
||||
Now we can have a detailed look in `dbg.log` to find out what's going wrong. Open `dbg.log` and search for `UNRESOLVED` (or `FAIL` if that's what you're looking for):
|
||||
|
||||
---------------------------------------------------------
|
||||
UNRESOLVED: Tab should complete ssh known-hosts at prompt
|
||||
---------------------------------------------------------
|
||||
|
||||
From there, search up for the first line saying:
|
||||
|
||||
-------------------------------------------------
|
||||
expect: does "..." match regular expression "..."
|
||||
-------------------------------------------------
|
||||
|
||||
This tells you where the actual output differs from the expected output. In this case it looks like the test "ssh -F fixtures/ssh/config <TAB>" is expecting just hostnames, whereas the actual completion is containing commands - but no hostnames.
|
||||
So what should be expected after "ssh -F fixtures/ssh/config <TAB>" are *both* commands and hostnames. This means both the test and the completion need fixing. Let's start with the test.
|
||||
|
||||
----------------------------
|
||||
$ vi lib/completions/ssh.exp
|
||||
----------------------------
|
||||
|
||||
Search for the test "Tab should complete ssh known-hosts". Here you could've seen that what was expected were hostnames ($hosts):
|
||||
|
||||
-----------------------------------------
|
||||
set expected "^$cmd\r\n$hosts\r\n/@$cmd$"
|
||||
-----------------------------------------
|
||||
|
||||
Adding *all* commands (which could well be over 2000) to 'expected', seems a bit overdone so we're gonna change things here. Lets expect the unit test for `_known_hosts` assures all hosts are returned. Then all we need to do here is expect one host and one command, just to be kind of sure that both hosts and commands are completed.
|
||||
|
||||
Looking in the fixture for ssh:
|
||||
|
||||
-----------------------------
|
||||
$ vi fixtures/ssh/known_hosts
|
||||
-----------------------------
|
||||
|
||||
it looks like we can add an additional host 'ls_known_host'. Now if we would perform the test "ssh -F fixtures/ssh/config ls<TAB>" both the command `ls` and the host `ls_known_host` should come up. Let's modify the test so:
|
||||
|
||||
--------------------------------------------------------
|
||||
$ vi lib/completions/ssh.exp
|
||||
...
|
||||
set expected "^$cmd\r\n.*ls.*ls_known_host.*\r\n/@$cmd$"
|
||||
--------------------------------------------------------
|
||||
|
||||
Running the test reveals we still have an unresolved test:
|
||||
|
||||
----------------------------------
|
||||
$ ./runCompletion ssh.exp --debug
|
||||
...
|
||||
=== completion Summary ===
|
||||
|
||||
# of expected passes 1
|
||||
# of unresolved testcases 1
|
||||
----------------------------------
|
||||
|
||||
But if now look into the log file `dbg.log` we can see the completion only returns commands starting with 'ls' but fails to match our regular expression which also expects the hostname `ls_known_host':
|
||||
|
||||
-----------------------
|
||||
$ vi dbg.log
|
||||
...
|
||||
expect: does "ssh -F fixtures/ssh/config ls\r\nls lsattr lsb_release lshal lshw lsmod lsof lspci lspcmcia lspgpot lss16toppm\r\nlsusb\r\n/@ssh -F fixtures/ssh/config ls" (spawn_id exp9) match regular expression "^ssh -F fixtures/ssh/config ls\r\n.*ls.*ls_known_host.*\r\n/@ssh -F fixtures/ssh/config ls$"? no
|
||||
-----------------------
|
||||
|
||||
Now let's fix ssh completion:
|
||||
|
||||
-------------------
|
||||
$ vi ../contrib/ssh
|
||||
...
|
||||
-------------------
|
||||
|
||||
until the test shows:
|
||||
|
||||
----------------------------------
|
||||
$ ./runCompletion ssh.exp
|
||||
...
|
||||
=== completion Summary ===
|
||||
|
||||
# of expected passes 2
|
||||
----------------------------------
|
||||
|
||||
Fixing a unit test
|
||||
~~~~~~~~~~~~~~~~~~
|
||||
Now let's consider a unit test failure. First you're triggered by unsuccessful tests:
|
||||
|
||||
----------------------------------
|
||||
$ ./runUnit
|
||||
...
|
||||
=== unit Summary ===
|
||||
|
||||
# of expected passes 1
|
||||
# of unexpected failures 1
|
||||
----------------------------------
|
||||
|
||||
Take a look in `log/unit.log` to find out which specific command is failing.
|
||||
|
||||
-----------------
|
||||
$ vi log/unit.log
|
||||
-----------------
|
||||
|
||||
Search for `UNRESOLVED` or `FAIL`. From there scroll up to see which `.exp` test is failing:
|
||||
|
||||
------------------------------------------
|
||||
/@Running ./unit/_known_hosts_real.exp ...
|
||||
...
|
||||
FAIL: Environment should stay clean
|
||||
------------------------------------------
|
||||
|
||||
In this case it appears `_known_hosts_real.exp` is causing the problem. Isolate the `_known_hosts_real` test by specifying just `_known_hosts_real.exp` to run. Furthermore add the `--debug` flag, so output gets logged in `dbg.log`:
|
||||
|
||||
----------------------------------
|
||||
$ ./runUnit _known_hosts_real.exp --debug
|
||||
...
|
||||
=== completion Summary ===
|
||||
|
||||
# of expected passes 1
|
||||
# of unexpected failures 1
|
||||
----------------------------------
|
||||
|
||||
Now, if we haven't already figured out the problem, we can have a detailed look in `dbg.log` to find out what's going wrong. Open `dbg.log` and search for `UNRESOLVED` (or `FAIL` if that's what you're looking for):
|
||||
|
||||
-----------------------------------
|
||||
FAIL: Environment should stay clean
|
||||
-----------------------------------
|
||||
|
||||
From there, search up for the first line saying:
|
||||
|
||||
-------------------------------------------------
|
||||
expect: does "..." match regular expression "..."
|
||||
-------------------------------------------------
|
||||
|
||||
This tells you where the actual output differs from the expected output. In this case it looks like the the function `_known_hosts_real` is unexpectedly modifying global variables `cur` and `flag`. In case you need to modify the test:
|
||||
|
||||
-----------------------------------
|
||||
$ vi lib/unit/_known_hosts_real.exp
|
||||
-----------------------------------

Within test scripts the following library functions can be used:

|
||||
== The test environment
|
||||
[[Test_context]]
|
||||
== Test context
|
||||
|

The tests run in a specially prepared bash environment. The following files are used:
|
||||
* bashrch
|
||||
* inputrc
|
||||
* fixtures
|
||||
The test environment needs to be put to fixed states when testing. For instance the bash prompt (PS1) is set to the current test directory, followed by an ampersand (@). The default settings for `bash` reside in `config/bashrc` and `config/inputrc`.
|
||||
|
||||
For each tool (completion, install, unit) a slightly different context is in effect.

|

=== What happens when tests are run?
|
||||
|

==== completion
|
||||
|
||||
When the completions are tested, invoking DejaGnu will result in a call to `completion_start()` which in turn will start `bash --rcfile config/bashrc`.
