Field Detail

compiler

private final SequenceCompiler compiler

The compiler for sequence code.

junitCreator

private final JUnitCreator junitCreator

The JUnitCreator to generate a class from a ExecutableSequence

classNameGenerator

private final NameGenerator classNameGenerator

The name generator for temporary class names.

methodNameGenerator

private final NameGenerator methodNameGenerator

The name generator for test method names.

genTests

private final GenTests genTests

The GenTests instance that created this predicate.

Constructor Detail

CompilableTestPredicate

public CompilableTestPredicate(JUnitCreator junitCreator,
                               GenTests genTests)

Creates a predicate using the given JUnitCreator to construct the test class for each sequence.

Parameters:

junitCreator - the JUnitCreator for this Randoop run

genTests - the GenTests instance to report compilation failures

Method Detail

close

public void close()
           throws java.io.IOException

Releases resources held by this.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Throws:

java.io.IOException

test

public boolean test(ExecutableSequence eseq)

Indicate whether the given sequence is compilable.

Specified by:

test in interface java.util.function.Predicate<ExecutableSequence>

Returns:

true if the sequence can be compiled, false otherwise

testSource

boolean testSource(java.lang.String testClassName,
                   com.github.javaparser.ast.CompilationUnit source,
                   java.lang.String packageName)

Return true if the given source code compiles without error. This is here to allow the mechanics of the predicate to be tested directly. Otherwise, we have to create a broken ExecutableSequence, which may not always be possible.

Parameters:

testClassName - the name of the test class

source - the source text for the class

packageName - the package name for the test, null if no package

Returns:

true if the code compiles (without error), false otherwise
