We present ExLi, a tool for automatically generating inline tests, which were recently proposed for statement-level code (i.e., target statement) validation. ExLi is the first tool to support retrofitting inline tests to existing codebases, towards increasing adoption of these types of tests. ExLi first extracts inline tests from unit tests that validate methods that contain the target statement under test. Then, ExLi uses a coverage-then-mutants based approach to minimize the set of initially generated inline tests while preserving their fault-detection capability. ExLi works for Java, and we use it to generate inline tests for 615 target statements in 30 open-source projects. ExLi reduces the initially generated 24,449 inline tests to 738. ExLi improves the fault-detection capability of test suites from which inline tests are generated: the final set of inline tests kills up to 30.3% more mutants on target statements than developer written and automatically generated unit tests. ExLi is open sourced at https://github.com/EngineeringSoftware/exli and a video demo is at https://youtu.be/qaEB4qDeds4.
