+
+The Problem
+
+# How can we refactor half a million lines of code without causing any side effects?
+
+---
+
+Motivation
+
+# Candidate Solution A
+
+```java
+Output newOutput = newSystem(testcase);
+Output oldOutput = oldSystem(testcase);
+compare(newOutput, oldOutput);
+```
+
+<div class="h-10" />
+
+## Disadvantages
+
+- Test is difficult to setup
+- Test system is inefficient to run
+- Test system is not reusable
+
+---
+
+Motivation
+
+# Candidate Solution B
+
+```java
+Output newOutput = newSystem(testcase);
+File newFile = writeToFile(testcase, newOutput);
+File oldFile = findOldFile(testcase);
+compare(newFile, newOutput);
+```
+
+<div class="h-10" />
+
+## Disadvantages
+
+- Dealing with files is no fun
+- Test system is hard to maintain
+- Test system is not reusable
+
+---
+
+Motivation
+
+# Candidate Solution C
+
+```java
+final Output newOutput = newSystem(testcase);
+final Description newDescription = describe(testcase, newOutput);
+submit(testcase, newDescription);
+```
+
+<div class="h-10" />
+
+## Disadvantages
+
+- Limited customization
+- Overkill for small projects
+- Requires remote computing resources
+
+---
+
+Motivation
+
+# Simple Example
+
+```java
+public record Student(
+  String username,
+  String fullname,
+  LocalDate dob,
+  double gpa
+) {}
+
+public static Student findStudent(final String username) {
+  // ...
+}
+```
+
+---
+
+Motivation
+
+# High-level API
+
+```java
+import io.touca.Touca;
+
+public final class StudentsTest {
+
+  @Touca.Workflow
+  public void findStudent(final String username) {
+      Student student = Students.findStudent(username);
+      Touca.assume("username", student.username);
+      Touca.check("fullname", student.fullname);
+      Touca.check("birth_date", student.dob);
+      Touca.check("gpa", student.gpa);
+  }
+
+  public static void main(String[] args) {
+    Touca.run(StudentsTest.class, args);
+  }
+}
+```
+
+---
+
+Motivation
+
+# Design Requirements
+
+- Intuitive developer experience
+- Intrinsic support for common types
+  - Must support integral types, fractional types, Strings, Iterables,
+    and other common standard types
+- Extensible design to support user-defined types
+  - Must allow users to introduce logic for handling custom types
