Test-driven Development (TDD) mit Angular 2 / 4

Vor kurzem habe ich zusammen mit Jan Massenberg von Setlog einen Vortrag über Test-driven development (TDD) mit Angular beim 2. Angular Ruhr Meetup gehalten. Aktuell unterstütze ich die Setlog GmbH bei der Verbesserung der Software Qualität und insbesondere bei der Entwicklung eines SaaS Tools, das Qualitätssicherungsprozesse (QA) im Supply Chain Management vereinfacht. Der Vortrag handelte von praktischen Erfahrungen mit TDD bei der Implementierung dieses SaaS Tools. Dieser Artikel fasst die wesentlichen Aspekte des Vortrags zusammen und beschreibt verschiedene Bestandteile eines Test-driven Design- und Entwickungsprozesses: ...

Agile Med Dev: Software Testing for Medical Devices

Leider ist der Eintrag nur auf English verfügbar.Medical devices software engineer Julien Zaegel wrote an interesting series of articles on medical devices software testing. These articles provide an overview of as well as several useful insights on the specifics of testing medical devices software and software in general. When it comes to automated and manual software testing for medical devices there are several aspects you don't usually have to deal with when testing more common kinds of web or business applications: With medical ...

JHipster: Generate And Bootstrap CRUD Apps With Spring Boot And Angular

Leider ist der Eintrag nur auf English verfügbar.The previous two posts in my series on helpful tools for developing CRUD applications were about tools that addressed very specific problem areas: API format specifications and code generation from those specifications in particular. This post will be both less about APIs and solving specific CRUD-related problems but about a tool that deals with CRUD app requirements in a comprehensive manner. This tool I'm talking about is called - not so slightly tongue-in-cheek - JHipster. Both ...

Swagger: A Roundtrip Tool For Creating And Consuming REST APIs

Leider ist der Eintrag nur auf English verfügbar.In this second part of my series on useful tools for developing CRUD applications I'd like to introduce Swagger and Swagger Codegen in particular. Introduce perhaps isn't exactly the right word because first of all Swagger is quite well known in developer circles these days. Secondly, a few months ago I wrote a blog post about how to use Swagger to generate client SDKs for REST APIs. Swagger - originally having originated at Wordnik is ...

Annotate and validate data structures with JSON Schema

Leider ist der Eintrag nur auf English verfügbar.I'd like to begin my little series of useful tools for developing CRUD applications with JSON Schema: "JSON Schema is a vocabulary that allows you to annotate and validate JSON documents." JSON Schema gives you a straightforward way to provide type information and validation to existing data structures. Say, for example you have a product instance like this (converted from your language's native object or general data structure format using a tool like Jackson for Java): [code ...

Why Do We Still Write CRUD Applications?

Leider ist der Eintrag nur auf English verfügbar.Probably every software developer - since the 1990s at least - has been there once, asking him- or herself: "Why do I have to write tedious, repetitive CRUD code time and time again?" Being good, virtuous programmers some of those developers did what software development in the end mostly is about: They tried to automate a cumbersome, repetitive process that like any repetitive process should be performed by machines rather than humans. Some have succeeded ...

Using Netflix Zuul As a Reverse Proxy / API Gateway

Leider ist der Eintrag nur auf English verfügbar.Zuul, which like the service discovery tool Eureka and the fault tolerance library Hystrix is part of Netflix' cloud orchestration stack, is a reverse proxy / API gateway. A reverse proxy conceptually works like this: A reverse proxy allows you to route requests to a single domain to multiple backing services behind that proxy. This can be conducive in situations where you want to break up your application into several loosely-coupled components that externally, that is ...

Designing Delivery and Moving Beyond Products

Leider ist der Eintrag nur auf English verfügbar.I'm a frequent attendee at Lean DUS, a regular event organised by the fantastic folks of sipgate. At LEAN DUS #23 earlier this year Jeff Sussna gave a talk on moving beyond products and unifying design and operations. Jeff runs a consulting company called Sussna Associates, which aims to help businesses to establish a comprehensive, continuous service delivery process. He also condensed his expertise in a book called Designing Delivery, which outlines a continuous value creation ...

Using Swagger to Generate Client SDKs for REST APIs

Leider ist der Eintrag nur auf English verfügbar.These days Swagger is a popular, easy-to-use tool for (semi-)automatically documenting REST APIs on-the-fly. For example, in order to document a REST API created with Spring Boot and Jersey literally all you have to do is add these two entries to your Maven pom.xml: [xml] <dependency> <groupid>io.springfox</groupid> <artifactid>springfox-swagger2</artifactid> <version>2.6.1</version> </dependency> <dependency> <groupid>io.springfox</groupid> <artifactid>springfox-swagger-ui</artifactid> <version>2.6.1</version> </dependency> [/xml] You'll then get a ready-made documentation for all your REST API endpoints. An example of how this looks like can be seen here. While this already is very useful in that it ...

Should Web Apps Behave More Like UNIX Programs?

Leider ist der Eintrag nur auf English verfügbar.Recently, through various discussions about the nature of the web and web applications I came up with an intriguing (to me at least ...) idea: Web apps should behave like UNIX command-line tools. Please hear me out and let me elaborate. Probably the most widespread pattern in modern web app development is that of single-page applications (SPAs). Though that particular term isn't used as abundantly anymore as it used to be a few years ago the ...
