Continuous Execute Java Class Using Build xml
4.1. Process
-
Create a file in the main folder:
.gitlab-ci.yml -
Describe expected treatments
-
"Push" on the GitLab repo
-
Control results
4.2. Example
image: node:4.2.2 (1) all_tests: script: (2) - npm install express --save - node ./myapp.js
| 1 | Name of the "runner" |
| 2 | Instructions for the virtual machine |
Results :
Figure 4. Attention au code infini
Another .gitlab-ci.yml:
- npm install express --save - node ./specs/start.js ./specs/async.spec.js
