Safe design and operation of chemical processes requires a thorough understanding of chemical reactivity and thermokinetics. IoKinetic offers a 3 step approach, applicable for relief system design, process optimization, and chemical reactivity hazard evaluation. Testing web applications is hard, and testing reactive web applications is even harder. Requirement based testing technique is another important alternative for building and prioritizing testing conditions.
To add to this, recent research has also identified strong relationships between reactive strength and offensive and defensive agility in Australian football players (13). As a result, it appears reactive strength is an important physical quality for acceleration, agility, and change of direction speed. An example of an integration test in our Reactive Microservice context could be calling the Application Router function and validate the integration between the different blocks (handler, processor etc.), and the external data source. Integration with data stores and external components provides early feedback on the system behavior.
Proactive vs Reactive White Box Testing
Fully tested source code is a measure of the quantity of source code within your application that is actually being tested. A deeper definition would be a measure of the quantity of complex business logic within your source code that is actually being tested. Learn from a world-class coach how you can improve your athletes’ agility.
- The reactive strength index measures the reactive jump capacity of athletes, and how they cope with the stress from plyometric exercises.
- In the middle of the activity diagram, there is another black-box, checking monthly max transfers exceeded, that can only truly be tested via white box testing.

- An athlete with lower technical proficiency (i.e. movement quality) appears to struggle to replicate plyometric activities such as DJs.

The incremental DJ-RSI can also be used to provide recommendations for an athlete’s optimal drop height for plyometric exercises (9). Figure 1 provides a clear example of a performance drop-off after a given drop height – in this case at 80 cm. This integration test calls the application router function of the microservice under test and validates the response received.
An event stream is steered either by the handlers themselves where work is dispatched to a specific next process, or by a message bus such as an enterprise service bus or message queue that carries the message to designated bus listeners. But streams generated by software-inserted observers are a bit more complicated. Normally, these elements work either in cooperation with the processing work done by an application or they run periodically to monitor a database element. When this software element recognizes a condition, it generates an event in the stream. Could you test all six of these conditions via black box testing, most likely not.
Separating the components from each other provides the advantage of thoroughly acceptance test the behavior of the component. While we will be discussing more around the implementation of the two testing phases, you’ll find that the implementation principles are very similar, however, it needs careful test designs to avoid duplication. While the integration tests focus more on validation of the integration interface code with the persistent layer and external systems, the component tests are focused towards the business functionality validations and its different variations. The amount of time and number of resources that would have to react to correcting such a catastrophe would be extensive and extremely costly.

Therefore, using the incremental DJ-RSI test may not be a useful test for sprinters, as their ground contact times are significantly faster. In this instance, alternative RSI tests such as the 10/5 may be more applicable due to the shorter ground contact times and the higher frequency of jumps. Practitioners should be well aware of this issue when testing their athletes and pick a test that better suits the demands of their athletes.
This test treats our component as black-box and validates the business requirements. The third-party service contract provides two different types of response structures (success and error response schema). For example, taking off in the long jump, or even changing direction in football both require the athlete to rapidly move through the stretch-shortening cycle. In fact, the RSI has been shown to have a strong relationship with both change of direction speed and acceleration speed (12).
There are many valid and reliable tests used to measure the reactive strength index – the most common of which is the incremental drop jump test. While the integration tests validate the interactions of the external modules & persistence layer (data-store), however, these tests do not take care of the business logic validations. The Component Tests are responsible to validate the business logic in the microservices. Although this can be achieved by the end-to-end system integration tests, SIT tests are slow and highly dependent on the external systems. The primary objective of the Component Tests is examining the system behavior in isolation.
A familiar problem in testing based on requirements is confusing specifications that are not complete, difficult to test and at times not available at all. If the organization does not take care of these issues, the testers must choose some other testing strategy. There are several techniques that can be used for choosing test conditions. The risk based strategy for testing was discussed in the previous section, which is one of the commonly used techniques by Test Managers for choosing tests. Let’s consider that there’s a DatabaseService class that implements the persistence layer. It also exposes a method called findById(id), that returns the document from the datastore.
Profile is one of the key features of the Spring framework, and it allows us to map beans to the different profiles (in loose terms can be called as environments as well). This feature enables us to create a component test profile that can have the configuration to stub all the external systems. This will provide us with the advantage of isolating our system under test from any external dependency. Unit testing takes care of validating the implementation of the functional blocks (unit), however, it does not provide guarantee about the behavior of the system. To verify that each module correctly collaborates with its interacting modules more coarse-grained testing is required. A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations.
Flight time is quite simply the total time the athlete is in the air during a jump – from when they break contact with the floor, to when they first touchdown upon landing. This is often measured using a jump/ contact mat, however, results can be easily influenced by body position during take-off and landing. For example, if an athlete bends their legs during flight, this can alter the results and affect the accuracy of the test. Furthermore, as well as being a useful marker for measuring performance and training progress, the RSI tests are also commonly used to measure neuromuscular fatigue during competition periods in team sports (10, 11).
For the business logic defined within this activity diagram, a minimum of six white box tests will be necessary to fully test transferring money from a savings account to a checking account. The reactive strength index measures the reactive jump capacity of athletes, and how they cope with the stress from plyometric exercises. This test first creates a stub for the external system in the @BeforeAll method, by running the same on port 9900 (as defined in the annotation). The ComponentTests class is a Junit class as our custom annotation @ComponentTest takes care of all the prerequisites. The test takes a simple payload as input and sends a request with all required headers and validates the response on execution.
For calling the service, a WebTestClient is instantiated with bindToRouterFunction method. This will create the POST request to the service and get the response back from the application. The response received is parsed to get the response body and validate further. This test achieves the validation of the integration interfaces with the datastore. As Martin Fowler defines, “An integration test verifies the communication paths and interactions between components to detect interface defects”. In microservice architectures, integration tests are typically used to verify interactions between layers of integration code and the external components to which they are integrating.
