Basic Functional Tests

While performance testing is a core part of our DNA, the Basic Functional Test is the first thing we look at. This functional test will brings up a system, install the complete software package, and measure a collection of Hello World type tests.

Each test is hand written to the specific piece of software under test and ensures that everything installs and runs as expected. 

The Basic Functional Test is not complex, but it is essential.

TEST DOCUMENTATION

CIDR Overview

Here at Ampere we believe in full automation and continuous best practices for all of our development activities. To meet our goals of a fully automated software environment we built a system called CIDR: Continuous Integration, Delivery, and Regression. 

CIDR is a framework composed of industry-best tools sitting on top of a robust database and analysis layer. This is all built using Python, Django, Postgres, serverless cloud environments, and more. We use CIDR to ensure that all of our systems and software meet the rigorous quality needs of the modern data center. 

Our CIDR data analysis tools are purpose-built to handle both functional and performance tests, giving us a complete picture of how our software performs on real hardware.

Results and data that you see in the CI/CD section of this portal are all collected using the CIDR infrastructure with Ampere bare-metal at its core. 

Find more details in our [All About CIDR](https://solutions.amperecomputing.com/posts/all-about-cidr) article.

CONTINUOUS INTEGRATION, DELIVERY, REGRESSION

Verified vs. Unverified

Results are categorized as either 'Verified' or 'Unverified'. Verified: Everything ran according to plan and results came back positive Unverified: We couldn't collect a result due to an issue within the test infrastructure. When we root-cause an Unverified result the write-up will appear in the Test Notes section of this page. An unverified test result does not imply an issue with the software under test - it means only that Ampere was unable to confirm one or more steps in our verification process.

DockerHub Image Pull Limits

On November 22nd, 2020 we noticed random failures across our DockerHub infrastructure. This was caused by a failure to authenticate with DockerHub following the rollout of rate limiting ([see here](https://docs.docker.com/docker-hub/download-rate-limit/)).

This presented with an error message similar to the following:

> *You have reached your pull rate limit. You may increase the limit by authenticating and upgrading...*

We rolled out a fix to authenticate with our DockerHub organization. 

This affected results collected between November 20th, 2020 and November 25th, 2020.

Overview

The Tuned system tuning tool is used to monitor the system to optimize its performance under certain conditions. The Tuned tool uses the udev device manager to monitor connected devices, enabling both static and dynamic tuning of your system's settings. You can use the tuned-adm recommend command to determine which profile is recommended for a particular product.

Ampere Computing's platforms are uniquely designed to meet the needs of the modern cloud native workload. Ampere's CIDR regression infrastructure uses images taken from a variety of sources. In this case, Tuned Profile OCI Recommend tracks the open source project found [here](https://docs.oracle.com/en/operating-systems/oracle-linux/8/monitoring/admin-tuned.html#about-tuned). The regression runs on bare metal rather than in a container.  Results are found below in the Test Results section of this page.
