You’re a senior developer at Travel World Agency (TWA). The company has built a next-generation system that uses a microservice architecture running on Amazon Web Services (AWS), and wants to prepare it for cost-cutting measures. Your task is to review the microservices architecture, create an architecture test using ArchUnit, create custom tests as needed, streamline update and creation processes by externalizing your tests to a single library, and integrate your architecture tests into a Jenkins pipeline. When you’re done, you’ll have a unit test that validates the structure of a microservices architecture.

You’re a senior developer at Travel World Agency (TWA). Management is surprised at the amount computing costs have increased, but before introducing potentially disruptive cost-reducing measures they need to determine how to improve the quality of the microservices. Your task is to simulate random problems, using Spring Boot’s Chaos Monkey library, to determine whether any scenarios exist that aren’t addressed by the code. To test your conclusions, you’ll use the Chaos Toolkit to generate concrete problems. When you’re done, you’ll have the skills to spotlight issues that aren’t always revealed through unit testing.

You’re a senior developer at Travel World Agency (TWA). As its success has grown, so have computing costs. But before introducing potentially disruptive cost-cutting measures into its next-gen system running on Amazon Web Services (AWS), it needs to improve the quality of its microservices. Your task is to detect possible security problems using Sonar, then use Dependency-Check and Dependency-Track to analyze the dependencies and add rules to define how many vulnerabilities your microservices might have with the ongoing execution of the pipeline.

Travel World Agency (TWA) has enjoyed rapid growth, but its computing costs have risen along with its success. Before implementing potentially disruptive cost-reducing measures to their next-gen system running on Amazon Web Services (AWS), it needs to improve the quality of its microservices. As a senior developer, your task is to detect whether any change in the request/response of the endpoints might affect the rest of the microservices. You’ll use Pact to define the contract between multiple microservices using the HTTP method, the name of the endpoint, and the requests and responses. By the end, you’ll be able to detect problems that could result from a change to the name, HTTP method, or the attributes that contain the requests and responses of one endpoint.

You’re a senior developer at Travel World Agency (TWA). Its swift success has come with a high rise in computing costs. But before it introduces potentially disruptive cost-saving modifications to its next-gen system running on Amazon Web Services (AWS), it needs to improve the quality of its microservices architecture. Your job is to create API and performance testing using Karate and Gatling and apply a black-box approach that prevents anyone from changing what’s inside the microservices. You’ll test the connection with external services as well as with a database, then create a performance test with minimal configuration by reusing one of your API tests.
