Android apps will work in the background (Android Background Service) mode to listen to broadcast messages, push services, and many other features that extend the functionality of the app. Similarly, it comes with job scheduling.

MyJobScheduler.Java

Add Android JobScheduler, Job Scheduler starts from this class where we can find methods that will start and stop work.

This method deals with the job start where we can also initialize our MyJobExecutor.java class so that we can execute our task as the job starts.

import android.app.job.JobParameters; 
import android.widget.Toast; 

public class MyJobScheduler extends android.app.job.JobService { 

private MyJobExecutor jobExecutor; 

@Override 
public boolean onStartJob(final JobParameters params) { 
jobExecutor = new MyJobExecutor() {

@Override 
protected void onPostExecute(String str) { 
Toast.makeText(MyJobScheduler.this, str, Toast.LENGTH_SHORT).show(); 
jobFinished(params,false); 
} 
}; 
jobExecutor.execute(); 
return true; 
} 

@Override 
public boolean onStopJob(JobParameters params) { 
jobExecutor.cancel(true); 
return false; 
} 

}

User Acceptance Technique is widely used for its efficiency and effectiveness.If we followed all steps of User Acceptance correctly then it will increase the satisfaction of a Customer.

UAT is a process of verifying that a Software or a System works appropriately as per the User Requirement.The main purpose of this testing is to ensure that a software system is all set to be in front of users in a real world.This testing phase also known as Beta and End-user testing and is mostly considered during the web development process to ensure that software is ready for the final installation for the Client site.

Types of User Acceptance Testing

1. Alpha & Beta Testing: Alpha testing is done by the staff members only on an internal whereas beta testing includes the Customer's environment with the help of some customer who will going to use our System or Software.
2. Black Box Testing: This type of functional testing includes all functionalities of the System without knowing the internal code structure.
3. Contract Acceptance Testing: In Contract type testing, software is tested against some criteria which are already predefined in a proper contract.
4. Operational Acceptance Testing: This type of Acceptance testing ensure that all the workflow used in system are working properly.
5. Regulation Acceptance Testing: Compliance Acceptance Testing helps in investigate the software fulfils all the guidelines of legal and governmental process.

Criteria Before Perform User Acceptance Testing

1. Entire application code should be up to date.
2. Integration testing, unit testing and System testing must be completed before we perform User Acceptance Testing.
3. There should not be any high/medium faults in the Integration phase of Testing.
4. There must be no major defect in the Regression Testing.
5. All the error/defects must get solved which we face during the testing and then testing should be done again to verify the error got fixed or not.

Involvement of Users in User Acceptance Testing:

The group is most essential for the UAT must include real end users that will going to perform a test on your system.The stakeholder and other group must incorporated that means an individual of every group is involved in the development phase must be in the team.

Start User Acceptance Testing:

After the explanation of UAT as above, you must get clear about what and why UAT must include in the software development phase. Mainly there are total of four steps that must be considered but it will depend on the number of user that will take advantage of software. The main criteria that must be followed in the software are the ‘working’ requirement of the assembled application. You can easily get a hang of it from the stories of users or system requirements. The second step is to create some test cases for UAT. User Acceptance Testcases are the test steps sets, expected results and execution conditions must be developed for some specific purpose.

Conclusion

These are some main points of the User Acceptance Testing that is used in the development cycle. The projects are reduced to the like of any errors that are elevated and it will reduce the total work required in the maintenance or development phase.

We often hear the term motivation. We all are human and that’s why we all have emotions and motivation is the driving force behind our behavior. Let’s discuss this in detail.

What is Motivation?

Motivation is the desire to act in service of the Goals. It’s the most crucial objective in setting and attaining business objectives.

We can define the motivation by the line in the book ‘The War Of Art’ written by The author Steven Pressfield “At some point, the pain of not doing it becomes greater than the pain of doing it.”

Motivation is a powerful weapon for any organization yet a tricky one. Sometimes it’s really easy to get motivated and motivate others, other times it's nearly impossible to figure out how to motivate oneself and others as well.

Every choice has a price but when employees are motivated it is easier to bear the inconvenience of action than the remaining same. In other words, employees are at the level ‘ It’s Easier To Change Than The Remaining Same’

Scientists define motivation as a general willingness to do something. It is the set of psychological forces that compel you to take action.

Common Misconception about motivation

How does motivation come?

We all have this misconception that motivation arrives as a result of watching motivational videos or reading inspirational books but one of the most surprising things is Motivation often comes AFTER starting new behavior not BEFORE. It’s the result of an action, not the cause of it.

I hope you get a basic understanding of Motivation. To know more about the motivation stay in tune with upcoming HR Blogs.
