Implementations

impl K6ScriptGenerator

pub fn new(config: K6Config, templates: Vec<RequestTemplate>) -> Self

Create a new k6 script generator

pub fn generate(&self) -> Result<String>

Generate the k6 script

pub fn sanitize_k6_metric_name(name: &str) -> String

Sanitize a name into a valid k6 metric-name base, capped at K6_METRIC_NAME_BASE_MAX_LEN characters.

k6 rejects metric names longer than 128 chars, and our templates append suffixes like _latency, _errors, _stepN_latency — reserve room for the longest suffix and truncate the base name when needed. Truncation appends an 8-hex-char hash of the original name so distinct long names produce distinct metric names.

Examples:

• “short_name” -> “short_name”
• 200-char OperationId -> “_<8-hex-hash>”

pub fn sanitize_js_identifier(name: &str) -> String

Sanitize a name to be a valid JavaScript identifier

Replaces invalid characters (dots, spaces, special chars) with underscores. Ensures the identifier starts with a letter or underscore (not a number).

Examples:

• “billing.subscriptions.v1” -> “billing_subscriptions_v1”
• “get user” -> “get_user”
• “123invalid” -> “_123invalid”

pub fn validate_script(script: &str) -> Vec<String>

Validate the generated k6 script for common issues

Checks for:

• Invalid metric names (contains dots or special characters)
• Invalid JavaScript variable names
• Missing required k6 imports

Returns a list of validation errors, empty if all checks pass.
