Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. assertNotNull 'error-msg-4' "xxx there's no /x/y"

What is the expected output? What do you see instead?
The assertion above fails despite it should not.

What version of the product are you using? On what operating system?
# tested shunit2 versions: shUnit 2.1.5 and shUnit 2.0.3
# shell: GNU bash, version 3.2.48(21)-release (i686-pc-cygwin)
# uname -s: CYGWIN_NT-5.1
# uname -r: 1.5.25(0.156/4/2)
# uname -v: 2008-06-12 19:34
# uname -m: i686
# uname -p: unknown
# uname -i: unknown
# uname -o: Cygwin

Please provide any additional information below.
See attached file (test_assertNotNull.zip) that contains a test script and
the produced output for each of the tested version of shUnit.

Here's my replacement for line 267 of shUnit 2.1.5 to fix this:

  _shunit_escaped_test="${1//\\/\\\\}"
  _shunit_escaped_test="${_shunit_escaped_test//\$/\\\$}"
  _shunit_escaped_test="${_shunit_escaped_test//\`/\\\`}"
  _shunit_escaped_test="${_shunit_escaped_test//\"/\\\"}"
  assertTrue "${shunit_message_}" "[ -n \"${_shunit_escaped_test}\" ]"

And here are some additional test cases for
src/shell/shunit2_test_asserts.sh:testAssertNotNull():

  ( assertNotNull "x'b" >"${stdoutF}" 2>"${stderrF}" )
  th_assertTrueWithNoOutput 'not null, with single-quote' $? "${stdoutF}" "${stderrF}"

  ( assertNotNull 'x"b' >"${stdoutF}" 2>"${stderrF}" )
  th_assertTrueWithNoOutput 'not null, with double-quote' $? "${stdoutF}" "${stderrF}"

  ( assertNotNull 'x$b' >"${stdoutF}" 2>"${stderrF}" )
  th_assertTrueWithNoOutput 'not null, with dollar' $? "${stdoutF}" "${stderrF}"

  ( assertNotNull 'x`b' >"${stdoutF}" 2>"${stderrF}" )
  th_assertTrueWithNoOutput 'not null, with backtick' $? "${stdoutF}" "${stderrF}"

Looking at including a fix for this in 2.1.6. The code by wood4321 is a good 
start, but only works in some shells. 
I'll try to adapt it and make it portable.

I've added some improvements for strange chars (like single quotes), but so far 
they only work under OS X due to sed variations. (See CL# 312)
