yanglint testing

Testing yanglint is divided into two ways. It is either tested in interactive mode using the tcl command 'expect' or non-interactively, classically from the command line. For both modes, unit testing was used using the tcl package tcltest.

How to

The sample commands in this chapter using tclsh are called in the interactive or non-interactive directories.

How to run all yanglint tests?

In the build directory designated for cmake, enter:

ctest -R yanglint

How to run all yanglint tests that are in interactive mode?

In the interactive directory, run:

tclsh all.tcl

How to run all yanglint tests that are in non-interactive mode?

In the non-interactive directory, run:

tclsh all.tcl

How to run all unit-tests from .test file?

tclsh clear.test

or alternatively:

tclsh all.tcl -file clear.test

How to run one unit-test?

tclsh clear.test -match clear_ietf_yang_library

or alternatively:

tclsh all.tcl -file clear.test -match clear_ietf_yang_library

How to run unit-tests for a certain yanglint command?

Test names are assumed to consist of the command name:

tclsh all.tcl -match clear*

How do I get more detailed information about 'expect' for a certain test?

In the interactive directory, run:

tclsh clear.test -match clear_ietf_yang_library -load "exp_internal 1"

How do I get more detailed dialog between 'expect' and yanglint for a certain test?

In the interactive directory, run:

tclsh clear.test -match clear_ietf_yang_library -load "log_user 1"

How do I suppress error message from tcltest?

Probably only possible to do via -verbose ""

How can I also debug?

You can write commands interact and interpreter from 'Expect' package into some test. However, the most useful are the exp_internal and log_user, which can also be written directly into the test. See also the rlwrap tool. You can also use other debugging methods used in tcl programming.

Are the tests between interactive mode and non-interactive mode similar?

• regex \n must be changed to \r\n in the tests for interactive yanglint

I would like to add a new "ly_" function.

Add it to the ly.tcl file. If you need to call other subfunctions in it, add them to namespace ly::private.

I would like to use function other than those prefixed with "ly_".

Look in the common.tcl file in the "uti" namespace, which contains general tcl functions that can be used in both interactive and non-interactive tests.
