It can be frustrating to realize that env.CHANGE_ID is not defined in your jenkins job, just because the current job is a branch build and not a pull request build.

grpc-services are quite simple, focused and performance oriented services. Instead of calling them with a format that needs complex marshalling / unmarshalling, and making use of a standard http 1.1 connection, grpc has a dedicated (therefore faster) generated code for each type. This protocol also indexes data fields by number, which permits to shrink the… Read More »

Rendering react in Java

Before telling me that I am crazy, think about it again. There are plenty of ways to use server-side rendering today, and the practice of sending displayable data through the network has proven to be efficient : - rendering data logged in the same tool as for backend services - less client business logic, less… Read More »

spring-boot : declare yaml partials

How do I mock javax.sql.DataSource

By LiBePosted on Friday 31 July 2020Friday 31 July 2020Cat G33k, ProgrammesLeave a comment

This is the annoying question I have had to ask myself. Integration tests are pretty slow. Even when they use a dedicated database like H2 or Derby, they are still accessing dark infrastructure software layers to read / edit / write / flush data. I was wanting tests able to run in no time and… Read More »
