Page reuse Playwright Java for PowerApps Testing - java

I want to reuse a page using Playwright with Java so I speed up the running of tests.
I use a persistent context because of the login requirements on the project - organisation page and MFA. I tried implementing something similar to https://playwright.dev/java/docs/test-runners but I get a NullPointerException.
Login class:
public class PersistentLogin {
private static String userDataDirPath = "/Users/user/powerAppsTesting/userData";
public static Page persistentLogin(Boolean headlessState){
Playwright playwright = Playwright.create();
BrowserType chromium = playwright.chromium();
Path userDataDir = Paths.get(userDataDirPath);
BrowserContext context = chromium.launchPersistentContext(userDataDir
, new BrowserType.LaunchPersistentContextOptions().setHeadless(headlessState));
Page page = context.newPage();
return page;
};
}
Tests class:
public class TestsExample {
private String goToUrl = "www.example.com";
Page page;
#BeforeAll //also tried #BeforeEach but with the same result
void createPage(){
page = persistentLogin(true);
}
#Test
public void saveHolidayPeriodFromAdminScreenTest(){
//Page page = persistentLogin(true);
page.navigate(goToUrl);
page.frameLocator("#fullscreen-app-host").getByRole(AriaRole.BUTTON, new FrameLocator.GetByRoleOptions().setName("Run as Admin")).click();
assertThat(page.frameLocator("#fullscreen-app-host").getByText("Preferences - New Summer Leave 2023")).isVisible();
page.close();
}
Output:
java.lang.NullPointerException

I can't see what i am missing.
Thank you!


The page wasn't initialise before use, it was initialise only in #BeforeEach.
Page page1 = persistentLogin(true);
solves the issue.

Could not find FeatureManager when running test on REST API

I get this error when trying to run a test:
java.lang.IllegalStateException: Could not find the FeatureManager. For web applications please verify that the TogglzFilter starts up correctly. In other deployment scenarios you will typically have to implement a FeatureManagerProvider as described in the 'Advanced Configuration' chapter of the documentation.

Anything I can find on this talks about adding something like this wo web.xml:
<filter>
<filter-name>TogglzFilter</filter-name>
<filter-class>org.togglz.servlet.TogglzFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>TogglzFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
I'm working on a REST API so don't have a web.xml. I'm using Spring Boot 2.6.2 and Togglz version 3.2.1.
This is my Togglz configuriation:
#Configuration
public class TogglzConfiguration implements TogglzConfig {
public Class<? extends Feature> getFeatureClass() {
return FeatureOptions.class;
}
#Override
public StateRepository getStateRepository() {
return new InMemoryStateRepository();
}
#Override
public UserProvider getUserProvider() {
return new SpringSecurityUserProvider("admin");
}
}
Here's my featureOptions:
public enum FeatureOptions implements Feature {
#Label("Temporary driver")
TEMP_DRIVER;
public boolean isActive() {
return FeatureContext.getFeatureManager().isActive(this);
}
}
MyController:
public class MyController {
private FeatureManager featureManager;
public MyController(FeatureManager featureManager) {
this.featureManager = featureManager;
}
...
public ResponseEntity<MyResponse> tempDriver(#RequestBody
MyTempDriverRequest request) {
if (FeatureOptions.TEMP_DRIVER.isActive()) {
if (request
.getTempDriver()
.equals("")) {
request.getTempDriver().setCountry("GB");
}
}
...
}
My application.properties is:
togglz.console.enabled=false
togglz.console.secured=false
togglz.features.TEMP_DRIVER.enabled=true
togglz.console.use-management-port=false
One thing I do notice when I run the application v's my test is that in the application, my debugger show's the featureManager like this:
In the test, the debugger shows it like this:
How do I resolve this?

}
I think that this information is enaugh to know something about this problem (I could add that it works fine with real services so in my opinion problem is somewhere in MockServer configuration).

I think you forgot to close your resulting json
.withStatus(200).withBody("{\"token\":\"1234\"/n")))
should be
.withStatus(200).withBody("{\"token\":\"1234\"}/n")))

The solution was to change port of mock server.

Reactor proper way of throwing a common error from multiple reactive methods

I have a few reactive methods from which I want to throw a common exception when the stream is empty, e.g.:
import reactor.core.publisher.Mono;
import reactor.test.StepVerifier;
public class Test {
private final Mono<Integer> errorMono = Mono.error(() -> new Exception("Empty"));
#org.junit.Test
public void testErrors() {
function1(null)
.as(StepVerifier::create)
.consumeErrorWith(Throwable::printStackTrace)
.verify();
function2(null)
.as(StepVerifier::create)
.consumeErrorWith(Throwable::printStackTrace)
.verify();
function3(null)
.as(StepVerifier::create)
.consumeErrorWith(Throwable::printStackTrace)
.verify();
}
private Mono<Integer> function1(Integer input) {
return Mono.justOrEmpty(input)
.doOnNext(i -> System.out.println("Function 1 " + i))
.switchIfEmpty(errorMono);
}
private Mono<Integer> function2(Integer input) {
return Mono.justOrEmpty(input)
.doOnNext(i -> System.out.println("Function 2 " + i))
.switchIfEmpty(errorMono);
}
private Mono<Integer> function3(Integer input) {
return Mono.justOrEmpty(input)
.doOnNext(i -> System.out.println("Function 3 " + i))
.switchIfEmpty(errorMono);
}
}
For each of these methods, the exception stack trace originates from line 1, and I can't find out which of the methods were empty:
private final Mono<Integer> errorMono = Mono.error(() -> new Exception("Empty"));

How can I write a common exception throwing mechanism which will provide the correct function in stack trace?

Instead of relying a single Mono<Integer> errorMono = Mono.error(() -> new Exception("Empty"));, you can create a specific Mono.error to each function. Then you write the specific message on these Mono.error like the following:
private Mono<Integer> function1(Integer input) {
return Mono.justOrEmpty(input)
.doOnNext(i -> System.out.println("Function 1 " + i))
.switchIfEmpty(Mono.error(() -> new Exception("function 1")));
}
private Mono<Integer> function2(Integer input) {
return Mono.justOrEmpty(input)
.doOnNext(i -> System.out.println("Function 2 " + i))
.switchIfEmpty(Mono.error(() -> new Exception("function 2")));
}
private Mono<Integer> function3(Integer input) {
return Mono.justOrEmpty(input)
.doOnNext(i -> System.out.println("Function 3 " + i))
.switchIfEmpty(Mono.error(() -> new Exception("function 3")));
}
Then you will be able to see on the stack trace which function is throwing your error:
java.lang.Exception: function 1
at com.github.felipegutierrez.explore.advance.CustomExceptionTest.lambda$function1$2(CustomExceptionTest.java:30)
...
java.lang.Exception: function 2
at com.github.felipegutierrez.explore.advance.CustomExceptionTest.lambda$function2$4(CustomExceptionTest.java:36)
...
java.lang.Exception: function 3
at com.github.felipegutierrez.explore.advance.CustomExceptionTest.lambda$function3$6(CustomExceptionTest.java:42)

Android kotlin Unit test case..?

How to write the test-cases for the below function.
public void trackMaxInterval(int trackingFastestInterval) {
if (trackingFastestInterval != 0) {
preferencesManager.writeLong(Constants.INTERVAL, interval);
} else {
preferencesManager.writeLong(Constants.INTERVAL, Service.INTERVAL);
}
}
I tried like below code but getting a null point exception it saying PreferencesManager is null
#Test
fun shouldSaveTracking_MaxIntervalValue() {
val preManager: PreferencesManager = mock(PreferencesManager::class.java)
loginPresenter.trackMaxInterval(2)
verify(preManager, times(1)).writeLong(Constants.INTERVAL, 2)
}
Attached error log.

It looks like your loginPresenter object does not hold a reference to a PreferencesManager instance. Even if you mock your PreferenceMananger in your test, you have to pass it somehow to the loginPresenter object.

Assertj-swagger throws org.assertj.core.error.AssertJMultipleFailuresError Multiple Failures when executing test

I have a spring boot api application and I used springfox to generate swaggerv2 api documentation and I created a test to see if my api definitions are correct.
Heres how my configuration looks like:
#Configuration
#EnableSwagger2
public class SpringFoxConfig {
#Value("${my.app.version}")
private String appVersion;
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2).groupName("My App").select()
.apis(RequestHandlerSelectors.basePackage("my.com.app.controller"))
.paths(regex("/api/MyAppName.*")).build()
.globalOperationParameters(
Arrays.asList(new ParameterBuilder().name("UserKey").description("Unique user key.")
.modelRef(new ModelRef("string")).parameterType("header").required(true).build()))
.apiInfo(apiInfo()).securitySchemes(Arrays.asList(apiKey()));
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder().title("My App API Documentaion")
.description("This documentation is for the MyApp.").version(appVersion)
.license("MyApp.cc").licenseUrl("https://myapp.com/").build();
}
private ApiKey apiKey() {
return new ApiKey("apiKey", "APIKEY", "header");
}
}
Here's how my test looks:
#Test
public void shouldFindNoDifferences() {
File implFirstSwaggerLocation = new File(
MyTest.class.getResource("/swagger.json").getFile());
File designFirstSwaggerLocation = new File(
MyTest.class.getResource("/swagger.yaml").getFile());
SwaggerAssertions.assertThat(implFirstSwaggerLocation.getAbsolutePath())
.isEqualTo(designFirstSwaggerLocation.getAbsolutePath());
}
It's exactly what they have from their examples. When I run my test It throws this exception below:

I think I'm missing something.

It was my carelessness that resulted to this problem but thanks to Roddy's comment I was able to notice my mistake.
In my assertj-swagger.properties file there contains assertj.swagger.pathsPrependExpected=/v2 property that causes this issue.
