Now i provide you the test case with bug: Under Test Class : SourceCodeAppender Under Test Method : appendExtensionPostAssignSourceCode Case:

    @Test
public void appendExtensionPostAssignSourceCode_A$StringBuilder$String_Real$List_Real$String_Real() {
    LineBreakProvider lineBreakProvider = new LineBreakProvider(config,
            currentLineBreak);
    SourceCodeAppender target = new SourceCodeAppender(lineBreakProvider,
            indentationProvider);
    StringBuilder buf = new StringBuilder();
    String code = "DependencyFactory.build({arg});";
    String[] fromList = new String[] { "\\{arg\\}", "\\{instance\\}" };
    String to = "caseDependency";
    target.appendExtensionPostAssignSourceCode(buf, code, fromList, to);
    assertThat(buf.toString().trim(),
            is(equalTo("DependencyFactory.build(caseDependency);".trim())));
}
