 # tests
 Running the tests requires [node.js](http://nodejs.org/). To run the suite of API tests:
 
-	node test/runtests.js
+	node test/sanity/runtests.js
 
 ### cross-validation tests
 The in-repo tests are just sanity/API checks, to really test out the library, run the cross-validation tests. These
 test the classifiers on large sets of real training data and give an error value (between 0 and 1) that indicates how good the classifier is at training. You can run the default cross-validation tests with:
 
-	node test/runcv.js
+	node test/cvalidate/runcv.js
 
 (requires network access to the dbs of training data). Specify your own db and options to pass in:
 
-	node test/runcv.js --type=neuralnetwork --db=http://localhost:5984/nndata --options='{learningRate:0.6}'
+	node test/cvalidate/runcv.js --type=neuralnetwork --db=http://localhost:5984/nndata --options='{learningRate:0.6}'
 
 The db must be a [CouchDB](http://couchdb.com) database of JSON objects with 'input' and 'output' fields.
