unexpected error invoking equal_dcomp_instrumented

[boyan...@gmail.com]

Hi,

I've met the `unexpected error invoking equal_dcomp_instrumented` when I use Daikon to detect invariants against Closure project in defects4j dataset. From the exception stack trace, I think it is the accessible issue related to the instrumented code. Below I paste the detailed stack trace,

However, if I run the tests without DynComp, all the tests passed.

Below are the steps to reproduce the issue,

1. install defects4j, https://github.com/rjust/defects4j 

2. checkout the Closure1f using `defects4j checkout -p Closure -v 1f -w Closure1f`

3. go to Closure1f and compile the project using `defects4j compile`

4. compile the attached TestRunner.java

5. go to Closure1f and run `CLASSPATH=$(find "$PWD" -name '*.jar' -type f -printf ':%p\n' | sort -u | tr -d '\n'); java -Xmx43G -cp $DAIKONDIR/daikon.jar:build/classes/:build/test/$CLASSPATH:<TestRunner path> daikon.DynComp '--ppt-select-pattern=^com\.google\.javascript\.jscomp\.RemoveUnusedVars' TestRunner com.google.javascript.jscomp.CommandLineRunnerTest::testSimpleModeLeavesUnusedParams com.google.javascript.jscomp.CommandLineRunnerTest::testForwardDeclareDroppedTypes com.google.javascript.jscomp.CommandLineRunnerTest::testDebugFlag1 com.google.javascript.jscomp.IntegrationTest::testIssue787 com.google.javascript.jscomp.RemoveUnusedVarsTest::testRemoveGlobal1 com.google.javascript.jscomp.RemoveUnusedVarsTest::testRemoveGlobal2 com.google.javascript.jscomp.RemoveUnusedVarsTest::testRemoveGlobal3 com.google.javascript.jscomp.RemoveUnusedVarsTest::testIssue168b`, you will need to replace the <TestRunner path> to the path of the compile TestRunner at step 4.

Then you should see the issue. 

Please let me know if there are any problem to reproduce the issue. Thank you very much for your help and your time.

I’m pretty sure this is a duplicate of https://github.com/codespecs/daikon/issues/304. 

In my comments there I show a suggested way to work around your nonstandard way of calling Junit.  I believe your version of tr3.java would need to have little test methods for each of:

com.google.javascript.jscomp.CommandLineRunnerTest::testSimpleModeLeavesUnusedParams

com.google.javascript.jscomp.CommandLineRunnerTest::testForwardDeclareDroppedTypes 

com.google.javascript.jscomp.CommandLineRunnerTest::testDebugFlag1 

com.google.javascript.jscomp.IntegrationTest::testIssue787 

com.google.javascript.jscomp.RemoveUnusedVarsTest::testRemoveGlobal1 

com.google.javascript.jscomp.RemoveUnusedVarsTest::testRemoveGlobal2 

com.google.javascript.jscomp.RemoveUnusedVarsTest::testRemoveGlobal3 

com.google.javascript.jscomp.RemoveUnusedVarsTest::testIssue168b

 Let me know if this works,

Hi Mark,

Thank you for your help.

I wrote a helper as your example but it still reports the same exceptions in my original post.

Below is my test helper:

import org.junit.Test;

public class TestIt {

    @Test

    public void testIt() throws Exception {

         com.google.javascript.jscomp.CommandLineRunnerTest test = new com.google.javascript.jscomp.CommandLineRunnerTest();

         test.setUp();

         test.testSimpleModeLeavesUnusedParams();

    }

}

First to compile it and the command to run it should be `CLASSPATH=$(find "$PWD" -name '*.jar' -type f -printf ':%p\n' | sort -u | tr -d '\n'); java -Xmx43G -cp $DAIKONDIR/daikon.jar:build/classes/:build/test/$CLASSPATH:<TestHelper path> daikon.DynComp '--ppt-select-pattern=^com\.google\.javascript\.jscomp\.RemoveUnusedVars' org.junit.runner.JUnitCore TestIt`

Thank you again for your time.

Regards,

Bo Yang

I found the problem and a fix was checked into https://github.com/codespecs/daikon on May 12.  I believe you can use your original TestRunner as well.
