I am facing an error saying unsyntactic break, how do I resolve it?
I am writing a program to check the health endpoint of one of our APIs. So, before starting execution, I try to hit the health endpoint 5 times. If I get the desired response code during the 5 attempts, I break the loop and start test execution, else give a message saying the API is not healthy and stop the execution.
When the below function is executed, it results in an error saying unsyntactic break Can someone suggest a better way to address this? I am using cypress.
const maxRetry = Cypress.env('maxWarmUpRetries');
const sleepTimeMs = 200;
console.log(chalk.yellow('Checking API health before test execution...'));
let healthCheckResponse;
let healthStatusCode;
for (let i = 0; i < maxRetry>
console.log('Value of i is: ',i)
apiHelper.requestHealth.then(response=>{
healthCheckResponse=response;
console.log('healthCheckStatusCode: ',healthCheckResponse.status)
if (healthCheckResponse) {
healthStatusCode = healthCheckResponse.status;
if (healthStatusCode === 200) {
console.log(chalk.green('API is healthy, moving forward with execution >>'));
break;
} else {
console.log(chalk.yellow('Warm up - Checking API /health before test execution...'));
if (i === maxRetry - 1) {
console.log(chalk.red('Warm up - API /health is down!!! Suspending test execution.'));
break;
}
}
} else {
console.log(chalk.yellow('Warm up - Checking API /health before test execution...'));
if (i === maxRetry - 1) {
console.log(chalk.red('Warm up - API /health is down!!! Suspending test execution.'));
break;
}
}
})
}
});
Unsyntactic Break should be inside a loop, you are calling break inside a callback function , this is why you are getting unsyntactic break if you want to break from call back replace break with return but this won't break the outside for loop.
you should use await :
for (let i = 0; i < maxRetry xss=removed xss=removed xss=removed xss=removed>>'));
break;
} else {
console.log(chalk.yellow('Warm up - Checking API /health before test execution...'));
if (i === maxRetry - 1) {
console.log(chalk.red('Warm up - API /health is down!!! Suspending test execution.'));
break;
}
}
} else {
console.log(chalk.yellow('Warm up - Checking API /health before test execution...'));
if (i === maxRetry - 1) {
console.log(chalk.red('Warm up - API /health is down!!! Suspending test execution.'));
break;
}
}
Note: To use await the IT block or function inside which you are calling this code should be declared as asyn
eg:
it('should edit a new item', async () => {
for (let i = 0; i < maxRetry xss=removed xss=removed xss=removed xss=removed>>'));
break;
} else {
console.log(chalk.yellow('Warm up - Checking API /health before test execution...'));
if (i === maxRetry - 1) {
console.log(chalk.red('Warm up - API /health is down!!! Suspending test execution.'));
break;
}
}
} else {
console.log(chalk.yellow('Warm up - Checking API /health before test execution...'));
if (i === maxRetry - 1) {
console.log(chalk.red('Warm up - API /health is down!!! Suspending test execution.'));
break;
}
}

The "unsyntactic break" error typically occurs in programming when a break statement is used incorrectly. This error can be caused by the break statement being placed outside of a loop or switch case, or it being used in a context where it is not syntactically valid.
Here’s how you can resolve it:
Ensure break is inside a loop or switch case:
The break statement should only be used within loops (such as for, while, do-while) or switch cases. Check your code to ensure that all break statements are correctly placed.
# Example of correct usage in a loopfor i in range(10): if i == 5: break # This is correct# Example of correct usage in a switch case (in languages like C, C++)switch (expression) { case 1: // code break; // This is correct case 2: // code break; // This is correct}Check for misplaced break statements:
Review your code to find any break statements that are not within a loop or switch statement. Remove or relocate them as needed.
Ensure proper syntax:
Make sure your loops and switch cases are properly closed and that the break statement is within the correct scope.
# Example of incorrect usageif condition: break # Incorrect, this will cause an unsyntactic break errorUse proper indentation and structure:In languages like Python, indentation is crucial. Ensure that your code structure is correctly indented and that break is used within the correct block.
# Example of correct usage in Pythonwhile True: if some_condition: break # Correct, inside the loopIf you provide more details or a snippet of your code, I can offer more specific advice.
