This blog post will show how to use a custom annotation to ensure your unit/integration tests are all consistent with little effort.

• Dec 20, 2019 Customization of Asciidoctor PDF output asciidoctor This blog post was written for asciidoctor-pdf 1.x. If you are using asciidoctor-pdf 2.x, then be aware that you need to use pdf-themesdir and pdf-theme in the Maven configuration. So replace: <attributes> <pdf-stylesdir>${project.basedir}/src/main/asciidoc/theme</pdf-stylesdir> <pdf-style>pegus-digital</pdf-style> </attributes> with: <attributes> <pdf-themesdir>${project.basedir}/src/main/asciidoc/theme</pdf-themesdir> <pdf-theme>pegus-digital</pdf-theme> </attributes> Using Asciidoc (the markup language) with the Asciidoctor toolchain is one of our favorite ways to write documentation. We mainly use it to create API documentation from our REST API backends using Spring REST Docs. Asciidoctor supports a variety of output formats, where HTML and PDF are ones we used the most. While the default PDF output already looks very good, it is always nice to be able customize the output a bit to better align with the project the documentation is created for. This post will explain exactly how to do that.
