## Test strategy

The test strategy for **gitjet.ru** will involve the following steps:

1. Unit testing of core components (CI/CD pipeline, Docker image build process, Helm chart deployment)
2. Integration testing between the components
3. Manual rollout testing to ensure platform stability and functionality

## Test tactics

The test tactics for **gitjet.ru** will involve the following techniques:

1. Black box testing: Testing without prior knowledge of the system architecture or implementation details
2. White box testing: Testing with prior knowledge of the system architecture and implementation details
3. Regression testing: Testing against known issues to ensure that new changes do not introduce regressions

## Test cases (mapped to use cases)

### Use case 1: Deploying Platform via CI/CD Pipeline

**Test case:** Verify that the CI/CD pipeline correctly builds and publishes Docker images to the private registry.

**Tactic:** Black box testing

**Steps:**
1. Trigger a new commit to the `main` branch of the **[gitjet/core-scm](../core-scm)** repository.
2. Verify that the CI/CD pipeline builds and publishes Docker images to the private registry.

### Use case 2: Manual Rollout of Platform

**Test case:** Verify that the manual rollout script correctly deploys the platform changes.

**Tactic:** White box testing

**Steps:**
1. Execute the `core-scm/deploy/helm-upgrade-k3s-lab.sh` script to manually roll out the platform changes.
2. Verify that the platform is deployed correctly using Helm charts.

## Smoke

The smoke tests for **gitjet.ru** will involve the following components:

1. CI/CD pipeline (defined in `.gitjet/workflows/core-scm-production.yml`)
2. Docker image build process
3. Helm chart deployment

### Smoke test 1: CI/CD pipeline

**Test case:** Verify that the CI/CD pipeline is correctly configured and running.

**Tactic:** Black box testing

**Steps:**
1. Trigger a new commit to the `main` branch of the **[gitjet/core-scm](../core-scm)** repository.
2. Wait for the CI/CD pipeline to complete successfully.

### Smoke test 2: Docker image build process

**Test case:** Verify that the Docker image build process is correctly configured and running.

**Tactic:** Black box testing

**Steps:**
1. Build a new Docker image using the `docker build` command.
2. Verify that the image is built successfully.

### Smoke test 3: Helm chart deployment

**Test case:** Verify that the Helm chart deployment process is correctly configured and running.

**Tactic:** Black box testing

**Steps:**
1. Deploy the platform using Helm charts.
2. Verify that the platform is deployed successfully.

## Regression

The regression tests for **gitjet.ru** will involve the following components:

1. CI/CD pipeline (defined in `.gitjet/workflows/core-scm-production.yml`)
2. Docker image build process
3. Helm chart deployment

### Regression test 1: CI/CD pipeline

**Test case:** Verify that the CI/CD pipeline correctly handles errors and failures during the build and publish process.

**Tactic:** White box testing

**Steps:**
1. Introduce an error in the `.gitjet/workflows/core-scm-production.yml` file.
2. Trigger a new commit to the `main` branch of the **[gitjet/core-scm](../core-scm)** repository.
3. Verify that the CI/CD pipeline handles errors and failures correctly.

### Regression test 2: Docker image build process

**Test case:** Verify that the Docker image build process correctly handles errors and failures during the build process.

**Tactic:** White box testing

**Steps:**
1. Introduce an error in the `Dockerfile` of the **[gitjet/core-scm](../core-scm)** repository.
2. Build a new Docker image using the `docker build` command.
3. Verify that the image is built successfully and handles errors and failures correctly.

### Regression test 3: Helm chart deployment

**Test case:** Verify that the Helm chart deployment process correctly handles errors and failures during the deployment process.

**Tactic:** White box testing

**Steps:**
1. Introduce an error in the `Chart.yaml` file of the **[gitjet/core-scm](../core-scm)** repository.
2. Deploy the platform using Helm charts.
3. Verify that the platform is deployed successfully and handles errors and failures correctly.

## Edge cases

The edge cases for **gitjet.ru** will involve the following components:

1. CI/CD pipeline (defined in `.gitjet/workflows/core-scm-production.yml`)
2. Docker image build process
3. Helm chart deployment

### Edge case 1: CI/CD pipeline with multiple concurrent builds

**Test case:** Verify that the CI/CD pipeline handles multiple concurrent builds correctly.

**Tactic:** White box testing

**Steps:**
1. Trigger multiple new commits to the `main` branch of the **[gitjet/core-scm](../core-scm)** repository.
2. Verify that the CI/CD pipeline handles multiple concurrent builds correctly.

### Edge case 2: Docker image build process with large images

**Test case:** Verify that the Docker image build process handles large images correctly.

**Tactic:** White box testing

**Steps:**
1. Build a large Docker image using the `docker build` command.
2. Verify that the image is built successfully and handles large images correctly.

### Edge case 3: Helm chart deployment with multiple releases

**Test case:** Verify that the Helm chart deployment process handles multiple releases correctly.

**Tactic:** White box testing

**Steps:**
1. Deploy the platform using Helm charts multiple times.
2. Verify that the platform is deployed successfully and handles multiple releases correctly.
