Capstone: Test Data Management Utility

In real-world automation, hardcoding static emails leads to collision errors in parallel test runs. We build a utility that dynamically generates isolated test data payloads:

export class TestDataManager {
  static generateRandomUser(prefix = "user") {
    const timestamp = Date.now();
    return {
      username: ${prefix}_${timestamp},
      email: ${prefix}_${timestamp}@targetqa.com,
      role: "tester",
      createdAt: new Date().toISOString()
    };
  }
static async loadUserByRole(role) {
    if (!role) throw new Error("Role parameter is required");
    return { role, permissions: ["read", "write"] };
  }
}
