As a CEO, I care deeply about my company’s services' availability and functionality.

As a startup, we are constantly changing the architecture, adding services and changing service-endpoints and behaviors.

While monitoring the basic health signals is fairly simple and can be done by a variety of tools, monitoring my services' functionality and making sure that there are no functional failures is a pretty cumbersome job. It usually requires building functional tests in a programming language and then updating these tests whenever my service architecture changes. That can be really hard work! I needed a quick and easy to use solution to help me.

One of the use cases supported by UP9 is scriptless, automatically updating (self-healing) production testing that can also be used for functional monitoring.

I decided to use UP9 to monitor UP9’s availability and functionality.

Here is what I set out to achieve:

  • Get started in a few minutes without help from developers
  • Create a comprehensive test-suite that provides complete test-coverage for a few major workflows
  • Auto update the test-suite when my service architecture changes
  • Alert on failures

Scriptless, Synthetic Functional Monitoring Test-suite

To create the initial synthetic monitoring test-suite, I used the UP9 CLI which will launch a Puppeteer browser window that I'll use to record a few major workflows by simply using my application the way a user would.

up9 tap:start

The command opens a Puppeteer window, which I used to browse the UP9 production environment.

Observability in TEST1

When I go to my UP9 account, I can see my services, service-endpoints and related business logic which are quite familiar to me.

Observability-in Test

Automatically Generated Test-code that Covers the Business Logic

The ML model includes the service business logic that appears in the form of a graph with service-endpoints as nodes and dependencies as edges.

Observability Business Logic

UP9 automatically generates test-code that traverses the business logic graph providing complete test-coverage.

Machine Generated Test Code

The machine-generated test-code includes the API sequence, variable extraction and result assertions. All are automatically discovered without any user assistance. I can go in and customize the fail/success criteria to make it strict or relaxed, or modify the criteria.

Test Execution and Results Analysis

After a few minutes of customization and 'dialing in' the test-code, I ran it and then viewed the results in a 'single pane of glass'. I could see my system’s, services’ and endpoints’ reliability:

And in case there are failures, I can see what led to these failures (aka Root Cause Analysis):

Service Architecture Progression

As I mentioned earlier, as a startup everyday things change. Maybe there is a new service, or a different behavior from existing service-endpoints.

Traditionally, when the service architecture changes (aka Architecture Progression), old tests would break and I would have to update the tests or even regenerate them from scratch.

UP9 generates an architecture progression report that can be used to monitor my service architecture progression and see the changes:

Architecture Progression

Whenever UP9 identifies architecture changes, the test-code is automatically updated to match the up-to-date architecture and business logic.

Self-healing synthetic monitoring of service functionality is just one of the use cases of the modern test-automation provided by UP9.


UP9 is a microservice testing platform for Cloud Native systems that can scale across any number of services. UP9 helps developers prevent software regressions and increase engineering productivity through effortless testing and instant virtualization.

  • Understand how services interact with each other with automatic contract discovery.
  • Ensure system-wide contract adherence with tests that write themselves.
  • Start testing early with test environments as code, automatically mocking all service dependencies.

UP9 offloads the microservice testing workload from developers, giving them precious time back.

  1. Observability-in-Test is UP9's defenition of the collection of Observability artifacts in the context of TEST. I.e. the information a software engineer in test or a developer performing tests care about in the context of testing.
