nodejs redisClient with retry_strategy unit test
I am on learn unit testing phase using Sinon and Mocha with NYC report. I completely confuse how to cover this code
let client = redis.createClient({
retry_strategy: function(options) {
if (options.error) {
if (options.error.code === 'ECONNREFUSED') {
// End reconnecting on a specific error
// and flush all commands with a individual error
return new Error('The server refused the connection');
}
if (options.error.code === 'ECONNRESET') {
return new Error('The server reset the connection');
}
if (options.error.code === 'ETIMEDOUT') {
return new Error('The server timeouted the connection');
}
}
if (options.total_retry_time > 1000 * 60 * 60) {
// End reconnecting after a specific timeout and flush all commands
// with a individual error
logger.error('Retry time exhausted')
return new Error('Retry time exhausted');
}
if (options.attempt > 10) {
// End reconnecting with built in error
logger.error('Retry attempt exceed')
return undefined;
}
// reconnect after
return Math.min(options.attempt * 100, 3000);
},
...config, // my function pass this arguments
})
I tried to stub the redis.createClient
but it seems not cover the retry_strategy
(as a param) and it also ended up with unclosed coverage report.
Any thoughts or idea for me how to cover that retry_strategy statement and branches? or any approaches instead of stubbing?
Thank you
