Runs sequence of tests, preceded by valgrind call, with a command and arguments taken from file vtest.conf.
The arguments are dynamic because the vtest.conf entry can look like this:
# Arguments passed to $test_bin, evaluated at use (i.e. for each test separately)
test_bin_args='+Z -f $ZTST_srcdir/ztst.zsh $file' # runs ztst.zsh on given $file
test_bin="local-zsh" # expands to ../Src/zshThe variable $file is set to current test-file for each test-run. For Zsh-integrated valgrind tests, $file is just passed as argument to ztst.zsh. It comes from the outer loop in vruntests.zsh. So it is A01grammar.ztst, for example.
You can define errors so that they are skipped from test result (i.e. from Valgrind output). This is
the main feature of VATS because it allows to quickly check if changes broke anything. Usage is very
much like of unit tests – run make TESTNUM=A01, look for any red color, done. Zero parsing with
eyes. A typical definition for Zshell can look like this:
errors1+=( "* / zsh_main / setupvals / gettimeofday / *" )and is placed in __error1.def or other such file with index.
Following patch applied to the Test/Makefile solves the integration of VATS to Zsh:

test_bin="../Src/cgiturl" # Binary that runs any test (is the tested program itself)
zsh_control_bin="zsh" # Binary used when scheduling tests & interpreting Valgrind outputVariable zsh_control_bin is used to implement special #! behavior: runtests.zsh

user can define shebang interpreter via separate configuration file (vtest.conf).
The setting tkind is used to set a test-kind. These are modes of Valgrind operation.
Allowed values are: error (only detect read/write errors), leak (also detect memory leaks),
nopossiblylost (detect memory leaks, but not possibly lost blocks).
test_kind="leak" # Test kind: error, (leak|full - the same meaning), nopossiblylostValgrind messages of type summary and info are muted via lines:
summaries="no" # show valgrind summaries?

# Main
test_bin="local-zsh" # Binary that runs any test (local-zsh: ../Src/zsh)

# error definition that targets `a-function' doesn't match
mdebug="no" # Match-debug, use to debug error definition matching
interested_in="" # As if mdebug=1 (i.e. debugging of why an error-def matches
# or not), but only active if: stack trace and error definition
# contain $interested_in
#interested_in="*mk*temp" # Example value, will match error def:

#interested_in="(*locale*|*fork*|*printf*)" # Other example value - debugging multiple error-defs at once
