​

.deepsource.toml

This section covers .deepsource.toml configuration specific to the csharp analyzer. Please make sure to read the general configuration guide first.

​

name

• Type: String
• Presence: mandatory
• Description: Shortcode of the analyzer.
• Example:

name = "csharp"

​

enabled

• Type: Boolean

• Example:

enabled = true

​

meta

• Type: Table
• Presence: optional
• Description: Any supported metadata to pass to the analyzer.
• Example:

[analyzers.meta]
  cyclomatic_complexity_threshold = "high"

​

cyclomatic_complexity_threshold

• Type: String
• Presence: optional
• Description: Specify the acceptable risk category for your project as the threshold. All functions with complexity beyond this threshold will raise an issue. For example, setting the threshold to low will flag all functions that have a cyclomatic complexity of more than 5, while setting the threshold to critical will not flag any function.
• Available Values: low, medium, high, very-high and critical

• Default Value: medium
• Example:

cyclomatic_complexity_threshold = "high"

​

Sample config

version = 1

test_patterns = [
  "tests/**"
]

exclude_patterns = [
  "**/examples/**"
]

[[analyzers]]
name = "csharp"
enabled = true

  [analyzers.meta]
  cyclomatic_complexity_threshold = "high"

Code Coverage

​

Via dotnet test

Here are the steps to generate and report C# coverage data:

# Run your tests
dotnet test --collect:"XPlat Code Coverage" --logger:"console;verbosity=detailed" --results-directory /tmp/test-results/

# Install 'deepsource CLI'
curl https://deepsource.io/cli | sh

# Set DEEPSOURCE_DSN env variable from repository settings page
export DEEPSOURCE_DSN=https://sampledsn@deepsource.io

# From the root directory, run the report coverage command and provide the absolute file path to the generated report.
# In this case, the filepath looks something like /tmp/test-results/abcf7e0-b7df-4b0c-b919-7cb480d0f123/coverage.cobertura.xml
#
# Make sure to double check the test run ID, i.e. the GUID and the file path.
./bin/deepsource report --analyzer test-coverage --key csharp --value-file /tmp/test-results/<test_guid>/coverage.cobertura.xml
