+# Pragmatic Unit Testing: Summary
+
+## General Principles:
+- Test anything that might break Test everything that does break
+- New code is guilty until proven innocent Write at least as much test code as production code
+- Run local tests with each compile
+- Run all tests before check-in to repository
+
+## Questions to Ask:
+- If the code ran correctly, how would I know?
+- How am I going to test this? What else can go wrong? Could this same kind of problem happen anywhere else?
+- What to Test: Use Your RIGHT-BICEP Are the results right?
+- Are all the boundary conditions CORRECT? Can you check inverse relationships?
+- Can you cross-check results using other means?
+- Can you force error conditions to happen? Are performance characteristics within
+bounds?
+
+## Good tests are A TRIP
+- Automatic
+- Thorough
+- Repeatable
+- Independent Professional
+- Conformance
+
+## CORRECT Boundary Conditions
+- Does the value conform to an expected format?
+- Ordering — Is the set of values ordered or unordered as appropriate?
+- Range — Is the value within reasonable minimum and maximum values?
+- Reference - Does the code reference anything external that isn't under direct control of the code itself?
+- Existence - Does the value exist? (e.g., is non-null, non-zero, present in a set, etc.) 
+- Cardinality - Are there exactly enough values?
+- Time (absolute and relative) - Is everything happening in order? At the right time? In time?
