Examples with LocationInFile org.sonar.ucfg.LocationInFile used on opensource projects

Example 16 with LocationInFile

use of org.sonar.ucfg.LocationInFile in project sonar-java by SonarSource.

the class UCFGJavaVisitorTest method unknown_method.

@Test
public void unknown_method() {
    Expression.Variable arg = UCFGBuilder.variableWithId("arg");
    UCFG expectedUCFG = UCFGBuilder.createUCFGForMethod("A#method(Ljava/util/Set;)V").addMethodParam(arg).addBasicBlock(newBasicBlock("0").ret(constant("implicit return"), new LocationInFile(FILE_KEY, 9, 2, 9, 3))).build();
    String source = "import java.util.Set;\n" + "import java.util.Collection;\n" + "import java.util.stream.Collectors;\n" + "public class A {\n" + "  void method(Set<String> arg) { \n" + "    arg.stream()\n" + "      .flatMap(Collection::stream)\n" + "      .collect(Collectors.toCollection(LinkedHashSet::new)); \n" + "  }\n" + "}";
    // Semantic model creates 2 kinds of "unknown" symbols: "Symbols.unknownSymbol" and "JavaSymbolNotFound"
    // We need to test first case
    // To make sure that code contains "Symbols.unknownSymbol" this assertion is there
    // Note that if Semantic model is improved somehow that "Symbols.unknownSymbol" is not anymore generated in this case
    // this test might be removed
    assertUnknownMethodCalled(source);
    assertCodeToUCfg(source, expectedUCFG);
