Examples with RegexCheck org.sonar.java.regex.RegexCheck used on opensource projects

Example 1 with RegexCheck

use of org.sonar.java.regex.RegexCheck in project sonar-java by SonarSource.

the class DefaultJavaFileScannerContextTest method report_issue_on_regex_tree_with_secondary.

@Test
void report_issue_on_regex_tree_with_secondary() {
    RegexCheck regexCheck = new RegexCheck() {
    };
    String regex = "x{42}|y{23}";
    RegexTree regexTree = RegexParserTestUtils.assertSuccessfulParse(regex);
    DisjunctionTree disjunctionTree = (DisjunctionTree) regexTree;
    RepetitionTree x42 = (RepetitionTree) disjunctionTree.getAlternatives().get(0);
    CurlyBraceQuantifier rep42 = (CurlyBraceQuantifier) x42.getQuantifier();
    RepetitionTree y23 = (RepetitionTree) disjunctionTree.getAlternatives().get(1);
    CurlyBraceQuantifier rep23 = (CurlyBraceQuantifier) y23.getQuantifier();
    RegexCheck.RegexIssueLocation secondary = new RegexCheck.RegexIssueLocation(rep42, "regexSecondary");
    context.reportIssue(regexCheck, rep23, "regexMsg", null, Collections.singletonList(secondary));
    assertThat(reportedMessage.getMessage()).isEqualTo("regexMsg");
    assertThat(reportedMessage.getCost()).isNull();
    assertMessagePosition(reportedMessage, 3, 8, 3, 12);
    assertThat(reportedMessage.flows).hasSize(1);
    List<AnalyzerMessage> reportedSecondaries = reportedMessage.flows.get(0);
    assertThat(reportedSecondaries).hasSize(1);
    AnalyzerMessage reportedSecondary = reportedSecondaries.get(0);
    assertThat(reportedSecondary.getMessage()).isEqualTo("regexSecondary");
    assertThat(reportedSecondary.getCost()).isNull();
    assertMessagePosition(reportedSecondary, 3, 2, 3, 6);
}

Example 3 with RegexCheck

use of org.sonar.java.regex.RegexCheck in project sonar-java by SonarSource.
