cuke-tree is a interactive web based GUI/IDE for running Cucumber tests and viewing the results. cuke-tree scales to hundreds of cucumber tests. It works in situations where Cucumber's HTML reports simply can't cope with the number of test scnearios in a report.
With cuke-tree, the hierarchical, directory based structure of your feature files is visualized as a tree structure and you can select parts of the structure to quickly execute only the features under that part of the structure.
cuke-tree shows you the results of executing your scenarios directly in the browser and even renders Cucumber attachments/embeddings like web page screenshots when a test fails.
