运行测试时，如何让emacs苹果酒(clojure模式)使用我的测试环境变量? [英] How do I get emacs cider (clojure mode) to use my test environment variables when running tests?

问题描述

我已经为开发和测试环境设置了单独的database-url，当在REPL中以及在命令行中的lein test中运行我的webapp时，这很好用.这是我的profiles.clj:

I've set up separate database-url for development and test environments, and this works nicely when running my webapp in the REPL and from the lein test on the command line. Here's my profiles.clj:

{:profiles/dev  {:env {:database-url "wiki"}}
 :profiles/test {:env {:database-url "wiki-test"}}}

以及正确的数据库实例被击中的证据(我正在使用CouchDB):

And evidence of the right database instance being hit (I'm using CouchDB):

;; Running the site from the REPL:
[info] [<0.12149.0>] 127.0.0.1 - - GET /wiki/home-page 200
[info] [<0.10353.0>] 127.0.0.1 - - GET /wiki/about 200

;; Running lein test:
[info] [<0.12026.0>] 127.0.0.1 - - GET /wiki-test/welcome 404
[error] [<0.12933.0>] Could not open file /usr/local/var/lib/couchdb/wiki-test.c

但是，当我在Emacs中通过Cider运行测试时，它使用了开发环境，因此使用了错误的数据库实例.

However, when I run tests via Cider in Emacs it uses the dev environment and therefore the wrong database instance.

我该如何解决?

推荐答案

我建议您尝试使用with-redefs.

类似这样的东西:

(with-redefs [db (get-my-test-db)]
  (run-my-tests)

db是在测试中将数据库句柄绑定到的符号.

Where db is the symbol to which you bind your db handle in your tests.
