The test_server application has previously been deprecated.
In OTP 19, we will move relevant parts of test_server into the
common_test application. Test suites that include test_server.hrl
must be updated to include ct.hrl instead. Test suites that include
test_server_line.hrl must removed that inclusion. Test suites that
call the test_server module directly will continue to work in OTP 19.
The test suites for Erlang/OTP are built and executed in exactly
the same way as previously.
Here are some more details.
The modules test_server*.erl and erl2html2.erl in lib/test_server/src
have been moved to common_test/src.
The test_server.hrl and test_server_line.hrl include files have
been deleted. The macros in test_server.hrl have been copied into
lib/common_test/include/ct.hrl.
The ts*.erl modules and their associated data files in
lib/test_server/src has been been moved to the new directory
lib/common_test/test_server. The ts* modules are no longer built
to lib/common_test/ebin. They will only built when 'make release_tests'
is executed.
The test suite for test_server has been moved to lib/common_test/test.
The rest of the files have been deleted.

This adds a test function similar to the app file test function
existing in test_server. The code is mostly taken from the asn1,
snmp and inets test suites. Low-level upgrade instruction checking
is stripped. Library application's appup files get specialized
treatment, since their content is almost static.

The unicode update of test_server for R16A introduced a few potential
errors when logging to files. Sometimes ~tp or ~ts was used for
formatting also when writing to files that were not opened with the
{encoding,utf8} option. If then the argument contained unicode
characters above 255, the file descriptor would crash. This has been
corrected by the following modifications:
* Since the 'unexpected_io' log file is used only when the test case
HTML file is not available (e.g. between test cases), this file is
now also a HTML file and as other test_server HTML logs it is always
UTF-8 encoded
* Since it is possible to change which information is going to which
log file (with test_server_ctrl:set_levels/3), we do not have full
control over which information is written to which file. This means
that any printout could be written to the 'major' log file
(suite.log), which was earlier encoded as latin1. To avoid crashing
this file descriptor due to unicode strings, the 'major' log file is
now also encoded in UTF-8 (possible incopatibility).
* The cross_cover.info file is no longer a text file which can be read
with file:consult/1, instead it is written as a pure binary file
using term_to_binary when writing and binary_to_term when reading.
* The encoding of the file named 'last_name', which only content is
the path to the last run.<timestamp> directory, is now dependent on
the file name mode of the VM. If file names are expected to be
unicode, then the 'last_name' file is UTF-8 encoded, else it is
latin1 encoded.
Also, ~tp is changed back to ~p unless it is somehow likely that the
argument includes strings. It is not obvious that this is the correct
thing to do, but some decission had to be taken...
|
|
* Use UTF-8 encoding for all HTML files, except the HTML version of
the test suite generated with erl2html2:convert, which will have the
same encoding as the original test suite (.erl) file.
* Encode link targets in HTML files, allowing both special characters
like "/", "&", "?" etc, and latin1 or unicode characters.
* Use unicode modifier 't' with ~s and ~p when appropriate.
* Use unicode:characters_to_list and unicode:characters_to_binary for
conversion between binaries and strings instead of binary_to_list
and list_to_binary.

Line numbering of erlang files that were not correctly indented could
be wrong after coverting to html with erl2html2:convert/[2,3]. This has
been corrected.
This commit also fixes the following:
* There are now link targets for each line and not only for each 10th
line - meaning that links from test logs are now to the exact line,
and not to the last number for which N rem 10 == 0.
* there will only be one link target per function, i.e. the faulty
link targets for function clauses are removed.
* link targets for function now includes the arity (e.g. func/1 has a
link target "func-1")
And some tests are added.

Earlier, #st.config was set to undefined when entering this loop. Then
it was updated when the test case itself started. This means that if
the test case process crashed during test case initiation, the parent
process would not know the Config.
This commit saves the initial Config value in the parent process
(run_test_case_msgloop/1) from the start.

Before line numbers were included in exceptions (in R15), there were
parse transforms and macros that would keep the test_server_loc
process dictionary variable updated; therefore there is a mod_loc/1
function that will normalize the representation of locations.
Simplify the code as following:
* 'test_server_loc' should always contain a list with one or more
tuples. ({M,F} or {M,F,Line})
* At the beginning of each test case, set 'test_server_loc' to
[{Module,Func}] of the the currently executing test case.
* Stop updating 'test_server_loc', except when an exception occurs.
(It used to be updated when running 'init_per_testcase' and so on.)
* Remove the mod_loc/1 function.

Three pieces of information could be out of sync in testcase
supervisor process at the time when a timetrap occurred:
* test_server_loc (process dictionary) - may indicate that a
framework function is executing
* test_server_init_or_end_conf (process dictionary) - indicates whether
init_per_testcase or end_per_testcase is executing
* The current configuration (#st.config) - set using a synchronous
call
There could be in a crash in spawn_fw_call/7 because the current
configuration was not defined when it was expected to.
To avoid the problem, introduce set_tc_state/2 (and a corresponding
message) to allow setting both an indication what the testcase is
executing (e.g. init_per_testcase, framework call, and so on), and
the current configuration. Use only that information to handle
a timetrap timeout (and aborted testcase and the other reasons
for the testcase process to terminate). Completely remove
test_server_init_or_end_conf.

os:type/0 could (a long, long time ago) return atoms such as
'vxworks' instead of a two-tuple.

Remove the old kludgy parse transformations and line numbers
macros in common_test and test_server, and use the line numbers
in exceptions instead.

1. ct:timetrap(infinity) not supported.
2. Previous set timetrap for a test case is not cancelled by new one.

undefined

Directories added with run_test -pa or -pz in the pre erl_args part of the command line will be converted from relative to absolute, this to avoid confusion when Common Test switches working directory during the test run.
Also fixed in this commit: Problem with timeouts during init_tc or end_tc (in the Test Server framework).

Documentation still missing.
