Improved from last year's very popular session! How the "builder" pattern and the use of chained method calls (fluent API) helped us vastly improve our Java unit tests by making them more reliable, easier to read, write, and easier to merge. Our test engineers now use the same infrastructure, allowing them to write functional UI tests even faster (and they run faster, as well). As a by-product, builders helped our sales and demo teams create complex sample data quickly and easily. This session assumes that you're already familiar with writing JUnit tests.
