发展

碰撞版

准备

安装 bump2version。

预发布

选择遵循semver 规范的版本号类别。

测试颠簸版本

bump2version --dry-run --verbose $CATEGORY

其中是目标版本号类别名称，可能的$CATEGORY值为patch// minor。major

凹凸版

bump2version --verbose $CATEGORY

这会将版本设置为major.minor.patch-alpha.

发布

测试颠簸版本

bump2version --dry-run --verbose release

凹凸版

bump2version --verbose release

这会将版本设置为major.minor.patch.

运行测试

安装依赖项

python -m pip install -r requirements-tests.txt
