💡 Hint

Common Mistakes

Using 'prod' or 'dev' instead of 'test' when running tests.

The spring.profiles.active property sets the active profile. Here, test activates the test profile.

💡 Hint

Common Mistakes

Omitting quotes around the profile name.

Using the wrong profile name.

The @ActiveProfiles annotation activates the specified profile for the test class. Using "test" activates the test profile.

💡 Hint

Common Mistakes

Using 'active: test' under profiles instead of 'test'.

Misplacing colons or indentation.

In YAML, to define properties for a profile, use test after profiles:. So spring.profiles: test defines the 'test' profile section.

4fill in blank

hard

Fill both blanks to correctly inject a property value from the 'test' profile in a Spring component.

Spring Boot

@Value("$[1]")
private String [2];

Drag options to blanks, or click blank then click option'

Aapp.test.value

Bapp.prod.value

CtestValue

DprodValue

💡 Hint

Common Mistakes

Using a production property key when testing.

Variable name not matching the property meaning.

The @Value annotation injects the property named app.test.value. The variable name testValue is a good descriptive name for this property.

5fill in blank

hard

Fill all three blanks to create a test configuration class that activates the 'test' profile and defines a bean.

Spring Boot

@Configuration
@Profile([1])
public class TestConfig {

  @Bean
  public String sampleBean() {
    return [2];
  }

  public String getProfile() {
    return [3];
  }
}

Drag options to blanks, or click blank then click option'

A"test"

B"This is a test bean"

D"prod"

💡 Hint

Common Mistakes

Using the wrong profile name in @Profile.

Returning production strings in test beans.

The @Profile annotation activates the 'test' profile. The bean returns a test string. The method returns the profile name 'test'.
