I am writing a protractor testscript for my angular js webapplication. There is a jsonfile that I am using to fill in the data on the page. The try statement will look for the element that has the model property:
var data = {name: 'James', address: '11 Sussex street'};
for (key in data) {
try {
var el = element(by.model('name'));
if (el.isElementPresent()) {
el.clear().sendKeys(data[key]);
}
}
catch (err) {
console.log('error occured', err);
}
}
When I run the test now I get an error:
TypeError: Cannot read property 'findElementsOverride' of undefined
The name element is present but does not get set?
Try this instead
var el = element(by.model('name'));
el.isPresent().then(function(present) {
if (present) {
el.clear().sendKeys('James');
}
}).catch(err) {
console.log('error occured', err);
}

try {
myObject = {
a: JSON.stringify(obj)
};
} catch (err) {
logError(`myMethod :::: ${err.message}`);
}
I wanted to cover catch block under jest testcases but I am new to this jest test cases so I m not getting how to mock Json.stringify and how to throw error?
I am mocking as below. But I am getting error as: TypeError: Invalid JSON Can u please tell me where I am going wrong?
JSON.stringify = jest.fn().mockImplementationOnce(() => { throw new TypeError('Invalid JSON'); });
As I understand it, you want to test the catch part of your code. You can pass an invalid Json as an object.
So, if your function is:
function jestTest(obj) {
try {
myObject = {
a: JSON.stringify(obj)
};
} catch (err) {
logError(`myMethod :::: ${err.message}`);
}
}
module.export = jestTest
then, in your test function, you can use this:
var jestTestObject = require('./jestTest') // this hold your exported module, code which you are testing
JSON.stringify = jest.fn(); // do not mock to return "Invalid Json"
test("CatchPart", () => {
var invalidJson = ({ "a": 1}) // Create invalid json
var logErrorSpy = jest.spyOn(jestTestObject, 'logError') // spy on logError
jestTest(obj); // Invalid object will take it to catch part
expect(logErrorSpy).toHaveBeenCalledTimes(1) // which will call logError once
})
In the code below, when I run in debug mode with a break-point at this line: content.push(data.Body.toString()); I can see that data is inserted to the content array.
However when I run the code normally, content comes back empty.
How can I get it to populate the array for downstream use?
var params = { Bucket: "thebucket", Prefix: "theprefix/" }
var content = [];
function getS3Data()
{
var s3 = new aws.S3();
s3.listObjects(params, function (err, data)
{
if (err) throw err; // an error occurred
else
{
var i;
for (i = 0; i < data.Contents.length; i++)
{
var currentValue = data.Contents[i];
if(currentValue.Key.endsWith(params.Prefix) == false)
{
var goParams = { Bucket: params.Bucket, Key: currentValue.Key };
s3.getObject(goParams, function(err, data)
{
if (err) throw err; //error
content.push(data.Body.toString());
});
};
};
}//else
});//listObjects
}//getS3Data
getS3Data();
console.log(content); //prints empty here when run in non-debug.
The line:
console.log(content)
is being executed before the line:
content.push(data.Body.toString());
the function you are passing as a 2nd argument to s3.listObjects will be executed asynchronously. If you want to log out content you need to do it within the callback function meaning:
s3.listObjects(params, function (err, data) {
if (err) throw err;
else {
// ...
console.log(content)
}
});
A better approach would be to implement getS3Data with Promise so you can run code after the object listing is done for sure.
function getS3Data() {
return new Promise((resolve, reject) => {
if (err) {
reject(err)
} else {
const promises = []
for (const i = 0; i < data.Contents.length; i++) {
const currentValue = data.Contents[i];
if (currentValue.Key.endsWith(params.Prefix) == false) {
const goParams = { Bucket: params.Bucket, Key: currentValue.Key };
promises.push(new Promise((res, rej) => {
s3.getObject(goParams, function (err, data) {
if (err) {
rej(err); //error
} else {
res(data.Body.toString());
}
});
}));
}
}
Promise.all(promises).then(resolve);
}
});
}
getS3Data()
.then(result => { // this will actually be `content` from your code example
console.log(result);
}).catch(error => {
console.error(error);
})
Node.js' documentation has an example very similar to the problem you are experiencing:
Dangers of Mixing Blocking and Non-Blocking Code
The issue arises because the variable content is not set as soon as getS3Data has finished, because it is an asynchronous function. content will be set some time later. But your call to console.log(content); will execute immediately after getS3Data has finished, so at that point content has not been set yet.
You can test that by adding an extra log:
s3.getObject(goParams, function(err, data)
{
if (err) throw err; //error
content.push(data.Body.toString());
console.log("Content has been assigned");
});
And then change the bottom to:
getS3Data();
console.log("getS3Data has finished", content);
It's likely you'll get the messages in this order:
getS3Data has finished
Content has been assigned
I want to compare the data which I got from Mongo to javascript array. I am using lodash to compare. But it always return incorrect result.
var editUser = function(userData, getOutFunction) {
var status = CONSTANTS.NG;
checkExistUser(userData._id).then(function(user) {
if (user !== null) {
var userGroup = JSON.stringify(user.group);
user.group = user.group.map((groupId) => {
return groupId.toString();
});
var removedGroups = _.difference(userGroup, userData.group);
var addedGroups = _.difference(userData.group, userGroup);
console.log('Removed Groups: ', removedGroups);
console.log('Added Groups: ', addedGroups);
} else {
status = CONSTANTS.NG;
logger.debug(DEBUG_CLASS_NAME, "Cannot find object");
if (typeof(getOutFunction) !== 'undefined') {
getOutFunction(status, null);
} else {
NO_CALLBACK();
}
}
}).catch(function() {
console.log('Promise is error');
});
var checkExistUser = function(userId) {
return new Promise(function(resolve, reject) {
UserDAO.findById(userId, function(err, user) {
if (err) {
logger.debug(DEBUG_CLASS_NAME, {
name: err.name,
code: err.code,
message: err.message,
method: "checkExist"
});
resolve(null);
} else {
resolve(user);
}
});
});
}
For example:When I try to input value for lodash difference function
var user.group = ["58b8da67d585113517fed34e","58b8da6ed585113517fed34f"];
var userData.group = [ '58b8da67d585113517fed34e' ];
I want lodash difference return below result:
Removed Groups: ['58b8da6ed585113517fed34f']
Added Groups: []
However, the function gave me the result like:
Removed Groups: []
Added Groups: [ '58b8da67d585113517fed34e' ]
Can anyone help me in this case?
I will do appreciate it.
I have had this issue as well, the result from mongodb is an ObjectId type so you can compare the someObjectId.toString() value with your array of strings, or you could use
someObjectId.equals(stringOrObjectIdValue)
However, if you want to keep using lodash functions you will either have to force both arrays to strings or to ObjectIds before passing them into the function.
I just created a NodeJS cloudantDB web starter on bluemix. Then, I have a API get data from cloudantDB and get successfull but it returns all data. Please see js file:
js file:
app.get('/api/provider', function(request, response) {
console.log("Get method invoked.. ")
db = cloudant.use(dbCredentials.dbProvider);
var docList = [];
var i = 0;
db.list(function(err, body) {
if (!err) {
var len = body.rows.length;
console.log('total # of docs -> '+len);
if(len == 0) {
// error
} else {
body.rows.forEach(function(document) {
db.get(document.id, { revs_info: true }, function(err, doc) {
if (!err) {
if(doc['_attachments']) {
// todo
} else {
var responseData = createResponseDataProvider(
doc._id,
doc.provider_type,
doc.name,
doc.phone,
doc.mobile,
doc.email,
doc.logo,
doc.address
);
}
docList.push(responseData);
i++;
if(i >= len) {
response.write(JSON.stringify(docList));
console.log('ending response...');
response.end();
}
} else {
console.log(err);
}
});
});
}
} else {
console.log(err);
}
});
If I want to add parameter to API to get specific data from DB , Do we need create search index or query on cloudant, afer that call API the same : app.get('/api/provider/:id'). Please help me review and sharing. Thanks
you could get the document by id/name:
db.get(docID, function(err, data) {
// do something
});
references:
https://github.com/apache/couchdb-nano#document-functions
https://github.com/cloudant/nodejs-cloudant#api-reference
You can use a search function of Cloudant.
You need to create search index. In search index you can manage what data you want to get.
Example: https://cloudant.com/for-developers/search/
Following this code after create search index.
...
var query = {q: "id:doc.id"};
db.search('design document name', 'index name', query, function(er, result) {
if (er) {
throw er;
}
console.log(result);
});
I am trying to find out how to get cell changed event using the Excel object
Excel.run(function (ctx) {
}
in office 2016.
is the context used by Office.context.document is same as context used in run function
found the answer for this.
Binding concept used earlier can be used now also as shown in the example https://github.com/OfficeDev/office-js-docs/blob/master/reference/excel/bindingcollection.md
(function () {
// Create myTable
Excel.run(function (ctx) {
var table = ctx.workbook.tables.add("Sheet1!A1:C4", true);
table.name = "myTable";
return ctx.sync().then(function () {
console.log("MyTable is Created!");
//Create a new table binding for myTable
Office.context.document.bindings.addFromNamedItemAsync("myTable", Office.CoercionType.Table, { id: "myBinding" }, function (asyncResult) {
if (asyncResult.status == "failed") {
console.log("Action failed with error: " + asyncResult.error.message);
}
else {
// If successful, add the event handler to the table binding.
Office.select("bindings#myBinding").addHandlerAsync(Office.EventType.BindingDataChanged, onBindingDataChanged);
}
});
})
.catch(function (error) {
console.log(JSON.stringify(error));
});
});
// When data in the table is changed, this event is triggered.
function onBindingDataChanged(eventArgs) {
Excel.run(function (ctx) {
// Highlight the table in orange to indicate data changed.
var fill = ctx.workbook.tables.getItem("myTable").getDataBodyRange().format.fill;
fill.load("color");
return ctx.sync().then(function () {
if (fill.color != "Orange") {
ctx.workbook.bindings.getItem(eventArgs.binding.id).getTable().getDataBodyRange().format.fill.color = "Orange";
console.log("The value in this table got changed!");
}
else
})
.then(ctx.sync)
.catch(function (error) {
console.log(JSON.stringify(error));
});
});
}
})();
