• How to keep track/count of checked checkboxes in different menu's

  I implemented list of checkboxes in different menu's, how to keep count or track of checked checkboxes list. Issue: while changing on different menu's ... Ticked checkboxes again returning as uncheck action. writing code in js. example: Menu's: Speedo(its checkboxes: []x,[]y). Vmax(its checkboxes: []p,[]q,[]r). . .

• @ColumnResult maps to Character instead of String in JPA 2.0

  In our software, we had a requirement that display name of one UI will be configurable according to user. So one user want to display another column from one table and another user want to display another column from same table. I think I can do this using SqlResultSetMappings and automatic name query. display_name column is not in database . I think that I can map column name(according to user selection) to displayName. The problem, Jpa 2.0 does not have type in Columnresult annotation. So display name returns Character. This is my entity definition. In this eaxample user want to display short_name in the UIs. But another user can want to show name in the UIs.

  @SqlResultSetMappings({
      @SqlResultSetMapping(name = "findAllByTypeList", entities = @EntityResult(entityClass = Element.class, fields = {
              @FieldResult(name = "id", column = "ID"), @FieldResult(name = "variant", column = "VARIANT_ID"),
              @FieldResult(name = "elementType", column = "ELEMENT_TYPE_ID"),
              @FieldResult(name = "name", column = "NAME"), 
              @FieldResult(name = "shortName", column = "SHORT_NAME"),
              @FieldResult(name = "displayName", column = "display_name")
  
      }), columns = {
              @ColumnResult(name = "display_name")
      })
  })
   public class Element implements Serializable {
  /**

  private String displayName;
  
  public long getId() {
      return id;
  }
  
  public void setId(long id) {
      this.id = id;
  }

      this.variant = variant;
  }

      return ElementTypeConstants .getInstance(elementType);
  }

      this.elementType = elementType.getId();
  }
  
  public String getName() {
      return name;
  }
  
  public void setName(String name) {
      this.name = name;
  }
  
  public String getShortName() {
      return shortName;
  }
  
  public void setShortName(String shortName) {
      this.shortName = shortName;
  }
  
  public boolean equals(Object obj) {
      if (obj == null || !(obj instanceof Element)) {
          return false;
      }
      if (obj == this) {
          return true;
      }
      return ((Element) obj).getName().equals(this.getName());
  }
  
  public String toString() {
      StringBuffer buf = new StringBuffer("NE ID:");
      buf.append(getId());
      buf.append(", Name:");
      buf.append(getName());
      buf.append(", ShortName:");
      buf.append(getShortName());
      return buf.toString();
  }
  
  @Override
  public int hashCode() {
      return Long.valueOf(id).intValue();
  }
  
  public String getDisplayName() {
      return displayName;
  }
  
  public void setDisplayName(String displayName) {
      this.displayName = displayName;
  }
  

  This is my native query

  /** adding table name */
          sqlQuery = "select a.id, a.variant_id, a.ELEMENT_TYPE_ID, a.name, a.short_name,  a.short_name as display_name from " + conf_element a;
      Query query = em.createNativeQuery(sqlQuery
                      + " where a.variant_id=:variantId and a.element_type_id in (:elementTypeIdList)  order by a.name",
              "findAllByTypeList");
      query.setParameter("variantId", variantId);
      query.setParameter("elementTypeIdList", elementTypeList);
      return query.getResultList();
      }
  

  PS.: In the beginning, I think that I can implement without using ColumnResult.Following line can do the job.

          @FieldResult(name = "displayName", column = "display_name")

• Comparison of Unit test coverage tools for java

  Recently i was going through a few tools to measure the best unit test coverage for my java project.

  I came up with a few options and narrowed down the choices to these few

  (1) Chronometer

  (2) jacoco

  (3) Atlassian Clover

  (4) Cobertura

  i also tried to go through some of the comparisons.

  https://www.sealights.io/test-metrics/code-coverage-vs-test-coverage-pros-and-cons/

  https://confluence.atlassian.com/clover/comparison-of-code-coverage-tools-681706101.html

  But still couldn't figure out that using which one of these i can maintain a very good unit test coverage.

  a few basic requirements are

  (1) velocity coverage.

  (2) branch coverage.

  (3) function coverage.

  (4) line coverage.

  as multiple people are working so if any of these are below a defined threshold i don't want build to pass.

  Any help will be appreciated.
• React / Enzyme testing value of HTML Label?

  I want to test that my label component is properly parsing the data in the principal object.

  This is my label:

  <label id="userInfo"><b>Logged in as: </b>{principal.emailAddress}, <b>Role: </b>{userRole}</label>
  

  And this is my test, which is not currently working:

  describe("Testing User Info displaying correctly", () =>{
    it("when provided principal data, it should correctly combine the username and role", () => {
      expect(wrapper.find('[data-test-id="userInfo"]').text()).to.equal("Logged in as: jdoe@foo.bar, Role: Subscriber");
      });
  });
  

  How can I check that the value of my label, or more accurately the text between the tags, is being shown correctly?

  Currently the test fails with the following message:

  "Method “text” is only meant to be run on a single node. 0 found instead."

Everything works fine but the problem is when I click another link in my web application then my file is not downloading even the save download popup doesn't appear. I want to download the file in the background while I can surf other urls of my web app. I have tried using @Async but its not working giving a error like

  Scope 'session' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

  Maybe I am not doing it correctly? Can Anyone help me in this regard? please. here is my code.

  @SpringBootApplication
  @EnableAsync(proxyTargetClass=true)
  public class HrmoduleApplication extends SpringBootServletInitializer {
  
      @Override
         protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
             return application.sources(HrmoduleApplication.class);
         }
  
  
      public static void main(String[] args) {
          SpringApplication.run(HrmoduleApplication.class, args);
      }
      @Bean(name="processExecutor")
      public TaskExecutor workExecutor() {
  
          SimpleAsyncTaskExecutor asyncTaskExecutor = new SimpleAsyncTaskExecutor("spring_batch");
          asyncTaskExecutor.setConcurrencyLimit(SimpleAsyncTaskExecutor.UNBOUNDED_CONCURRENCY);
  
          return asyncTaskExecutor;
      }
  }
  

  in controller

  @GetMapping("/download")
  
      public ResponseEntity<byte[]>  downloadLeave(@RequestParam("monthNo") String monthNo,
              @RequestParam("yearNo") String yearNo, @RequestParam("companyId") String companyId,@RequestParam("status")String status) throws IOException, InterruptedException{
          //System.out.println("***********"+monthNo+" "+companyId);
          ResponseEntity<byte[]> responseByte=leaveService.downloadLeaveReportByStatus(companyId, status, monthNo, yearNo);
          return responseByte;
      }
  

  and in my service class method looks like

  @Async("processExecutor")
      @Override
  
      public ResponseEntity<byte[]> downloadLeaveReportByStatus(String companyId, String status, String month, String year) throws InterruptedException {
  
          String geturl = baseUrl + Endpoint.fetchEndpoint(ApiUrlList.KEY_GET_MONTHLY_LEAVE_LIST_BY_STATUS);
          System.out.println("comp "+companyId+" st "+status+" mon "+month+" year "+year);
  
          HttpHeaders headers = new HttpHeaders();
          restTemplate.getMessageConverters().add(new ByteArrayHttpMessageConverter());
  
          headers.setAccept(Arrays.asList(MediaType.APPLICATION_OCTET_STREAM));
          HttpEntity<String> entity = new HttpEntity<String>(headers);
  
          ResponseEntity<byte[]> response = restTemplate.exchange(geturl, HttpMethod.GET, entity, byte[].class, companyId,
                   status,month,year);
          Thread.sleep(1000);  
          //System.out.println(response.getBody());
  
          headers.setContentType(MediaType.parseMediaType("application/pdf"));
          String filename = "LeaveReport.pdf";
          headers.setContentDispositionFormData(filename, filename);
         // headers.setContentDispositionFormData("inline", filename);
  
          headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
          ResponseEntity<byte[]> responseByte = new ResponseEntity<>(response.getBody(), headers, HttpStatus.OK);
          return responseByte;
  
      }
  
• Is wireMock.Net able to handle json files from folders under "__admin/mappings" directory?

  I've developed a project using asp.net core 2.0 + wiremock.net. Currently, I'm able to handle json files under "__admin/mappings" directory only. However, I have several json files and because of that, I'd like to add one more folder under the "mappings" directory, for example "__admin/mappings/{anotherFolder}".

  What I have:

   __admin/mappings/first.json
   __admin/mappings/second.json
  

  What I would like to have:

   __admin/mappings/folder_A/first.json
   __admin/mappings/folder_A/second.json
   __admin/mappings/folder_B/first.json
   __admin/mappings/folder_B/second.json
  

  I've tried to add one more folder under the "mappings" folder, but when I tried to reach the json route, I got a message "No matching mapping found". Is there any way to handle json files from different directories?
• Wiremock Capture path param and return in the response body

  I am trying to create dynamic mocks using WireMock. I have a situation where if I specify URL like :

  http://localhost:8089/api/account/abc@abc.com
  

  then I should receive response like:

  { 
    "account" : "abc@abc.com" 
  }
  

  In brief, the path param is returned in the response body. I am able to make the request URL generic by using urlPathPattern set to /api/account/([a-z]*) however, I am not sure how should I capture abc@abc.com and return this in the response using regular expressions.
• Can mock-server or wiremock be used with Postman

  Can mock-server or wiremock be used with Postman as an alternative to the mock server provided by Postman?
• Spring Cloud Contract + Pact (Broker): json string can not be null or empty

  I've been experimenting with Contract Testing using Spring Cloud Contract (SCC) and am now trying to use Pact in combination with SCC to serve as an intermediate step before going pure Pact.

  On my consumer project I've specified a simple contract:

  @RunWith(SpringRunner.class)
  @SpringBootTest
  public class AccountServicePactTest {
      @Autowired
      TransactionService transactionService;
  
      @Rule
      public PactProviderRuleMk2 mockProvider = new PactProviderRuleMk2("account-service", "localhost", 8081, this);
  
      @Pact(consumer = "transaction-service")
      public RequestResponsePact createPact(PactDslWithProvider builder) {
          Map<String, String> headers = new HashMap<>();
          headers.put("Content-Type", "application/json;charset=UTF-8");
  
          return builder
                  .given("An account with UUID 8ea0f76b-b7a6-49eb-b25c-073b664d2de3 exists")
                  .uponReceiving("Request for an account by UUID")
                  .path("/api/accounts/8ea0f76b-b7a6-49eb-b25c-073b664d2de3")
                  .method("GET")
                  .willRespondWith()
                  .headers(headers)
                  .status(200)
                  .body("{\n" +
                          " \"accountUUID\": \"8ea0f76b-b7a6-49eb-b25c-073b664d2de3\",\n" +
                          " \"customerId\": 1,\n" +
                          " \"balance\": 0.00,\n" +
                          "}")
                  .toPact();
      }
  
      @Test
      @PactVerification
      public void runTest() {
          AccountRetrievalRequest request = new AccountRetrievalRequest(UUID.fromString("8ea0f76b-b7a6-49eb-b25c-073b664d2de3"));
          AccountDTO accountDTO = transactionService.retrieveAccount(request);
          assertThat(accountDTO.getAccountUUID()).isEqualTo(UUID.fromString("8ea0f76b-b7a6-49eb-b25c-073b664d2de3"));
      }
  
  }
  

  (I know that hardcoding the UUID, customerId and balance makes the test brittle, but this is just a simple test)

  Using the pact-jvm-provider-maven_2.12 plugin (provider plugin on consumer side, confusing I know) the Pact file gets pushed to a Pact Broker:

      <plugin>
          <groupId>au.com.dius</groupId>
          <artifactId>pact-jvm-provider-maven_2.12</artifactId>
          <version>3.5.22</version>
          <configuration>
              <pactBrokerUrl>http://localhost:8888</pactBrokerUrl>
              <pactBrokerUsername></pactBrokerUsername>
              <pactBrokerPassword></pactBrokerPassword>
              <trimSnapshot>true</trimSnapshot>
          </configuration>
          <executions>
              <execution>
                  <phase>install</phase>
                  <goals>
                      <goal>publish</goal>
                  </goals>
              </execution>
          </executions>
      </plugin>
  

  So far so good.

  On the provider project I run into issues trying to verify the the contract. Again, I'm using SCC and Pact together. pom.xml plugins snippet:

          </configuration>
      </plugin>
  

  SCC Verifier required Base Class:

  @RunWith(SpringRunner.class)
  @SpringBootTest(classes = AccountServiceApplication.class)
  public abstract class Account_serviceContractsBase {
      @Autowired
      private WebApplicationContext webApplicationContext;
      @Autowired
      private AccountRepository accountRepository;
  
      @Before
      public void setup() {
          Account account = new Account(UUID.fromString("8ea0f76b-b7a6-49eb-b25c-073b664d2de3"), Integer.toUnsignedLong(1),
                  0.00d);
          accountRepository.save(account);
          RestAssuredMockMvc.webAppContextSetup(webApplicationContext);
          System.out.println(account.getAccountUUID());
      }
  
      @After
      public void teardown() {}
  }
  

  SCC generated test:

  @FixMethodOrder(MethodSorters.NAME_ASCENDING)
  public class ContractsTest extends Account_serviceContractsBase {
  
      @Test
      public void validate_0_account_service_pact() throws Exception {
          // given:
              MockMvcRequestSpecification request = given();
  
          // when:
              ResponseOptions response = given().spec(request)
                      .get("/api/accounts/8ea0f76b-b7a6-49eb-b25c-073b664d2de3");
  
          // then:
              assertThat(response.statusCode()).isEqualTo(200);
              assertThat(response.header("Content-Type")).isEqualTo("application/json;charset=UTF-8");
          // and:
              DocumentContext parsedJson = JsonPath.parse(response.getBody().asString());
              assertThatJson(parsedJson).field("['accountUUID']").isEqualTo("8ea0f76b-b7a6-49eb-b25c-073b664d2de3");
              assertThatJson(parsedJson).field("['customerId']").isEqualTo(1);
              assertThatJson(parsedJson).field("['balance']").isEqualTo(0.0);
      }
  
  }
  

  Running the test gives the following exception:

  java.lang.IllegalArgumentException: json string can not be null or empty
  

  I can't figure out why the string is either empty or null. Running the application and using Postman to test the endpoint works just fine.

  This is part of the Controller:

  @RestController
  @RequestMapping("/api")
  public class AccountController {
  ...
      @GetMapping("/accounts/{accountUUID}")
      public ResponseEntity<Account> retrieveAccount(@PathVariable("accountUUID") UUID accountUUID) {
          HttpHeaders httpHeaders = new HttpHeaders();
          httpHeaders.add(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_UTF8_VALUE);
  
          return new ResponseEntity<>(accountService.retrieveAccount(accountUUID),
                  httpHeaders, HttpStatus.OK);
      }
  

  I'm missing something but I can't find what. Thoughts?

  EDIT: The (generated) test passed when just using SCC.
• Spring Cloud Contract : Stubs with same name get overridden in different folders

  We are doing consumer driven testing using spring-cloud-contract. I have two consumers (services) and one producer service. All of them are in different repositories. The producer has an api e.g. - /get/product/123. Each consumer has different requirements. So, I created two folders and put a getProduct.groovy file in each folder. It looks something like below:

  contracts │   ├── consumerA │   │   ├── GetProduct.groovy │   ├── consumerB │   │   ├── GetProduct.groovy

  Both groovy files contain different body, but generate stub json are same. It seems as if there can be only one groovy file with a name all the folders.

  How can I solve this problem?
• Intellij Idea hides my spring cloud contracts under test/resources

  I have written my first spring-cloud-contract using Intellij Idea 2018.2. Everything works fine, but I cannot edit the contract from within Idea because it hides the complete src/test/resources/contracts folder in the project view. So I have to individually open each contract vi the file -> open... menu.

  Can anybody tell me how I can access my contract files in Idea from the project view?
