Continuous Integration

Continuously testing your project is ensures a conflict-free shipping. For all the listed Continuous Integration provides, you will need a free account to enable building.

Travis

Travis has built-in support for D and building your project with D is as easy as adding to your .travis.yml the compilers to be tested :

# latest dmd, gdc and ldc
d:
  - dmd
  - gdc
  - ldc

You can also choose specific versions:

d:
  - dmd-2.071.0
  - ldc-1.0.0

Travis also offers OS X build environment, which you can enable by adding:

os:
 - linux
 - osx

More information is also available at Travis's documentation.

Testing 32-bit

All Travis containers use 64-bit, so if you want to test 32-bit is a bit tricky. One common trick is to use Travis build matrix feature to individually toggle extra builds as Mac OS X is x86-64 only since 10.7.

env:
 - ARCH="x86_64"
matrix:
  include:
    - {os: linux, d: dmd-2.071.0, env: ARCH="x86", addons: {apt: {packages: [[gcc-multilib]]}}}
    - {os: linux, d: ldc-1.0.0, env: ARCH="x86", addons: {apt: {packages: [[gcc-multilib]]}}}
script:
 - dub test --arch "$ARCH"

CircleCi

CircleCi doesn't support D out-of-the-box yet, but it is easy to install dmd and dub with a single line in your `circle.yml`:

dependencies:
  override:
    - source "$(curl -fsS  --retry 3 https://dlang.org/install.sh | bash -s dmd --activate)"
test:
  override:
    - dub test

AppVeyor (Windows)

Testing your project on Windows is currently a bit more complicated, but we are working on simplifying this integration. At the moment the best way to go is to extend your setup from this `appveyor.yml`:

platform: x64
environment:
 matrix:
  - DC: dmd
    DVersion: 2.071.0
    arch: x64
  - DC: dmd
    DVersion: 2.071.0
    arch: x86
  - DC: dmd
    DVersion: 2.070.0
    arch: x64
  - DC: dmd
    DVersion: 2.070.0
    arch: x86
  - DC: ldc
    DVersion: '1.0.0-alpha1'
    arch: x64
  - DC: ldc
    DVersion: 0.17.0
    arch: x64

If you have troubles with a specific version or compiler on Windows, you might want to allow failure in your build matrix until you get them fixed. For example to allow failure with ldc, you would add the following:

matrix:		
  allow_failures:		
    - DC: ldc
