Hi Deepika,If you want to quit in your present job you can change your field.But why you want to go in Software Testing?Either you have interest on that or just you want to change your job and take another one.If you are interested then no problem you can go for it.Because you should not repeat it again that after 2 years of doing work you want to change it again.It will be harmful for your career.First let me know your educational qualification so that I can suggest you more specifically.And if you want to go in Software IT field yes you can do software testing or web design ,web development,
