Simple clojure coverage tool. Currently requires clojure 1.4.

Add to :plugins in your .lein/profiles.clj

This library currently only supports clojure.test. You can get midje to work by wrapping facts in deftest declarations.

Run lein cloverage in your project. See cloverage/coverage.clj for more options.

To specify the version of cloverage manually, set the CLOVERAGE_VERSION to desired value, for example CLOVERAGE_VERSION=1.0.4-SNAPSHOT lein cloverage

By default, the plugin will use the latest release version of cloverage.

There is no maven plugin right now. A workaround is to import this library in the project being tested, then run: mvn exec:java -Dexec.classpathScope=test -Dexec.mainClass='clojure.main' -Dexec.args='--main cloverage.coverage *args-to-coverage*'

Where args-to-coverage will usually be something like "-n 'ns.regex.' -t 'test.ns.regex.'"

IllegalArgumentException No matching field found: foo for class user.Bar  clojure.lang.Reflector.getInstanceField (Reflector.java:271)

This is usually caused by protocols with methods starting with -. Before clojure 1.6:

user=> (defprotocol Foo (-foo [x] x))
Foo
user=> (deftype Bar [] Foo (-foo [_] "foo"))
user.Bar
user=> (-foo (Bar.))
"foo"
user=> ((do -foo) (Bar.))

IllegalArgumentException No matching field found: foo for class user.Bar  clojure.lang.Reflector.getInstanceField (Reflector.java:271)

Since cloverage will wrap the -foo symbol to track whether it's accessed, you will get this error. Upgrade to clojure 1.6.
