We Keep Coding

cy.saveLocalStorage is not a function Because this error occurred during a after each hook we are skipping the remaining tests in the current suite:

1
guys. I am very fresh in Cypress. Would like to get your help/advice: 1.For login I used below-mentioned way but I get error of: "cy.saveLocalStorage is not a functionBecause this error occurred during a after each hook we are skipping the remaining tests in the current suite: LoginFunctionality"
And I do not know where to store my credentials.
Support->Command.js
let LOCAL_STORAGE_MEMORY = {};
Cypress.Commands.add('saveLocalStorage', () => {
Object.keys(localStorage).forEach(key => {
LOCAL_STORAGE_MEMORY[key] = localStorage[key]
})
})
Cypress.Commands.add('restoreLocalStorage', () => {
Object.keys(LOCAL_STORAGE_MEMORY).forEach(key => {
localStorage.setItem(key, LOCAL_STORAGE_MEMORY[key])
})
})
Cypress.Commands.add('visitMultipleURL', url => {
cy.window().then(win => {
return win.open(url, '_self')
})
})
import 'cypress-iframe';
In login.spec.js
describe('LoginFunctionality', function () {
beforeEach(() =>{
cy.restoreLocalStorage();
Cypress.Cookies.defaults({
preserve: /[\s\S]*/,
})
})//
afterEach(() =>{
cy.saveLocalStorage();
})
let href;
it.only('LoginFunctionality', function () {
//cy.visit(Cypress.env('url'))
cy.visit('xxx')
cy.get('.chakra-stack > .css-1n94901').click()
cy.contains('Login with xxxx').click()
cy.url().then((url) => {
href = url;
cy.log('href ', href);
})
})
it.only('LoginFunctionality', function () {
cy.visit(href)
cy.url().should('include','xxxxx[![enter image description here][1]][1]')//assertion of that we are in this url
})
})

Something similar happened to me before.
I suggest you debug it by trying the code directly in your test first to check what's happening.
Also, do a console log in LOCAL_STORAGE_MEMORY and see if you have access to its value because cypress does not handle variables the way we would expect it if this was pure javascript (even when it might seem as if it's taking the value)
try
let LOCAL_STORAGE_MEMORY = {anyAttribute: "VALUE"};
To see if you get that attribute from inside the command
Usually that's what my problem was related to.

Structuring read/write characteristics code In React Native for ble-plx

needing a guide for how to layout functionality for a React Native app that's pairing with an ESP32 that will eventually feed back weight readings using read Characteristic, and be able to toggle a DI via write to a characteristic.
i can currently scan and connect to the ESP32 and show the values from the ESP32 (random changing values for now) and also toggle the LED via changing a hardcoded value. But i want to be able to do this via a button in the app.
const scanDevices = () => {
//set isLoading to true to show activity Indicator
setIsLoading(true);
//scan for devices, (UUIDs, ScanOptions(error, device))
manager.startDeviceScan(null, null, (error, device) => {
if (error) {
console.log("Error in scanning", error.message)
return;
}
if (device) {
//if a device is scanned, add the name & id details into the scannedDevice object via reducer
dispatch({type: 'DEVICE_ADD', payload: {name: device.name, id: device.id}});
}
});
//end scan after 3 seconds, stop the activity indicator swirly thing
setTimeout(() => {
console.log("Scan timeout after 5 seconds");
manager.stopDeviceScan();
setIsLoading(false);
}, 5000);
};
const deviceConnect = (device) => {
console.log("Connecting to:", device.name, device.id);
setIsConnected(true);
setConnectedDevice(device);
manager.connectToDevice(device.id)
.then((device) => {
console.log("Discovering all services & chars");
return device.discoverAllServicesAndCharacteristics()
}).then((device) => {
// console.log("Write Value inside deviceConnect:", writeValue)
console.log("Device:", device.name, "has been connected.");
return deviceNotifications(device, writeValue);
}).catch((error) => {
console.log("device connect error:", device.name, error)
//JSON.stringify(error)
});
};
const deviceNotifications = async (device, writeValue) => {
const service = "af493e2a-f002-11eb-9a03-0242ac130003";
const characteristicTX = "af49423a-f002-11eb-9a03-0242ac130003";
const characteristicRX = "af49414a-f002-11eb-9a03-0242ac130003";
if (device) {
try {
device.monitorCharacteristicForService(service, characteristicTX, (error, characteristic) => {
if (error) {
console.log(error);
} else {
setCharacteristicValue(() => {
return [{id: uuid.v4(), value: (base64.decode(characteristic.value))}];
})}
});
device.writeCharacteristicWithResponseForService(service, characteristicRX, base64.encode(writeValue));
console.log("Writing to RX:", writeValue);
}
catch (err) {
console.log("deviceNotification catch error:", err);
}
};
}
I'm getting pretty confused trying to sort through the [ble-plx documentation][1] ([github wiki][2])
Currently the only way i can get the LED to turn on/off, is i have the LED toggle section inside the deviceNotifications async function and have to manually change the value that's being encoded and written in the code itself, rather than from the App UI using an useState value.
I tried using the useState toggle off a button (which toggled the value and logged out OK), and then re-calling the deviceConnect function, but the commented out console.log in the .then promise section didn't work past the first one, returning which turned the LED on (writing 'A' to the characteristic).
thanks for any help in advance, i know a lot of these ble-plx questions go unanswered.
//this is at a top level inside the main function
const [writeValue, setWriteValue] = useState('A');
const toggleLED = () => {
if (writeValue == 'B') {
setWriteValue('A');
console.log("Toggling write value:", writeValue);
} else {
setWriteValue('B')
console.log("Toggling write value", writeValue)
};
};

Firebase Push Notification Not Popping Up

I successfully registered firebase service worker with
let messaging = null;
export const registerFirebaseServiceWorker = () => {
if ("serviceWorker" in navigator) {
console.log("serviceWorker in navigator");
navigator.serviceWorker.register(("./firebase-messaging-sw.js"))
.then((registration) => {
console.log("Registration successful, scope is: ", registration.scope);
})
}
}
and try to receive the message with messaging.onMessage callback
if (supportsWebPush) {
messaging.onMessage(payload => {
console.log("There's a message!", payload);
const notificationTitle = "notificationTitle"
const notificationOptions = {
body: payload
};
//self.registration.showNotification(notificationTitle, notificationOptions);
navigator.serviceWorker.getRegistration("./firebase-messaging-sw.js").then(registration => {
console.log("got the registration");
registration.showNotification('Hello world!');
}).catch(error => {
console.log("No service worker registered", error);
});
});
Even though console.log was working and registration.showNotification was executed, there were no push notification on my browser ? Why is this? I've been trying multiple different ways and search for many suspected issues but can't found a proper way to display default web push pop up

How to get value inside transaction result Firebase via node js

I'm building an iOS messenger app using Swift, Firebase and Nodejs.
My Goal:
Whenever a user sends a message and writes message data (such as senderId, receiverId, messageText) into a Firebase database inside node (/messages/{pushId}/), I want to make a message count increment by 1 using a transaction method that Firebase provides and display a notification to a receiver user.
Progress I've made so far and Problem I'm facing:
I've successfully increment message count (totalCount) using transaction method but I can't get value inside transaction result (Here's image of functions log )
I want to get "value_: 1"( this is the incremented message count) inside snapshot and put it to a badge parameter.
exports.observeMessages = functions.database.ref('/messages/{pushId}/')
.onCreate((snapshot, context) => {
const fromId = snapshot.val().fromId;
const toId = snapshot.val().toId;
const messageText = snapshot.val().messageText;
console.log('User: ', fromId, 'is sending to', toId);
return admin.database().ref('/users/' + toId).once('value').then((snap) => {
return snap.val();
}).then((recipientId) => {
return admin.database().ref('/users/' + fromId).once('value').then((snaps) => {
return snaps.val();
}).then((senderId) => {
return admin.database().ref('/user-messages/' + toId + '/totalCount').transaction((current) => {
return (current || 0) + 1
}).then((readCount) => {
console.log('check readCount:', readCount);
var message = {
data: {
fromId: fromId,
badge: //I want to display the message count here
},
apns: {
payload: {
aps: {
alert: {
title: 'You got a message from ' + senderId.username,
body: messageText
},
"content-available": 1
}
}
},
token: recipientId.fcmToken
};
return admin.messaging().send(message)
}).then((response) => {
console.log('Successfully sent message:', response);
return response;
})
.catch((error) => {
console.log('Error sending message:', error);
//throw new error('Error sending message:', error);
})
})
})
})
Does anyone know how to do this?
Thanks in advance.

The API documentation for transaction() suggests that the promise from the transaction will receive an object with a property snapshot with the snapshot of the data that was written at the location of the transaction. So:
admin.database.ref("path/to/count")
.transaction(current => {
// do what you want with the value
})
.then(result => {
const count = result.snapshot.val(); // the value of the count written
})

Send data using react-native-ble-plx package

In order to realize a project of connected objects. I need to implement a Bluetooth connection between the various devices.
Here, the goal is to create an application in React Native and then send data from this application to my Raspberry. This Raspberry has a connected HC-08 module that takes care of Bluetooth communication.
Now, I would like to use react-native-ble-plx library to send data through Bluetooth. I'm able to connect my Android to the module. But I don't understand how to send data ...
Here's my code :
constructor() {
super()
this.manager = new BleManager()
}
componentWillMount() {
console.log("mounted")
const subscription = this.manager.onStateChange((state) => {
if (state === 'PoweredOn') {
this.scanAndConnect();
subscription.remove();
}
}, true);
}
scanAndConnect() {
this.manager.startDeviceScan(null, null, (error, device) => {
if (error) {
// Handle error (scanning will be stopped automatically)
return
}
console.log(device.name)
// Check if it is a device you are looking for based on advertisement data
// or other criteria.
if (device.name === 'SH-HC-08') {
// Stop scanning as it's not necessary if you are scanning for one device.
this.manager.stopDeviceScan();
console.log(`Found ${device.name}`)
this.setState({
device: device
})
// Proceed with connection.
device.connect()
.then((device) => {
console.log(device)
return device.discoverAllServicesAndCharacteristics()
})
.then((device) => {
console.log(device)
})
.then((result) => {
// Do work on device with services and characteristics
//console.log(this.manager.characteristicsForService("00001800-0000-1000-8000-00805f9b34fb"))
console.log(result)
console.log("connected")
})
.catch((error) => {
// Handle errors
console.log(error)
});
}
});
}
send() {
this.manager.writeCharacteristicWithResponseForDevice("58:7A:62:4F:EF:6D",
this.device.serviceUUIDs[0],
this.manager.characteristicsForDevice(this.device.id),
"ok")
.catch((error) => {
console.log('error in writing data');
console.log(error);
})
}
I would like to have a send method that will send data whenever I want to. But I don't really understand how it works :/
Could someone help me or even give me an example ? I would be really appreciated.
Best regards.

I had success implementing the following:
scanAndConnect() {
this.manager.startDeviceScan(null, null, (error, device) => {
this.info("Scanning...");
console.log(device);
if (error) {
this.error(error.message);
return
}
if (device.name ==='MyDevice') {
this.info("Connecting to Tappy");
this.manager.stopDeviceScan();
device.connect()
.then((device) => {
this.info("Discovering services and characteristics");
return device.discoverAllServicesAndCharacteristics()
})
.then((device) => {
this.info(device.id);
device.writeCharacteristicWithResponseForService('12ab', '34cd', 'aGVsbG8gbWlzcyB0YXBweQ==')
.then((characteristic) => {
this.info(characteristic.value);
return
})
})
.catch((error) => {
this.error(error.message)
})
}
});
Where I use 12ab, insert the UUID of your BLE service. Similarly, where I use 34cd, insert the UUID of your BLE characteristic. Lastly, include a base64 encoding of whatever message you're trying to send where I have aGVsbG8gbWlzcyB0YXBweQ==.
Hope this helps.
