Let me clarify you..

Load testing is testing to see that how well the application maintains its performance under increased load.

for example they will see at what point the application is crashing. Testers increase all the available resources like hardware configuration of the systems, network speed i.e., what ever they can upgrade and test how many users (logins at a time) is handled by the application.

In stress we do the same as said above but with the limited resources available. here we do not upgrade the hardware or network speed or any thing. Just we test with the available resources.

hope this will clarify your doubt.

let me tell you in simple words.load testing is testing with large data base.stress testing is to test for large loades with long duration.any one plz correct me if iam wrong

If it is not cleared i will tell u tomorrow

In Load Test, we test number of users on application as per client requirements by applying gradually increase or at a time .Load testing is mainly based on giving the data only for mandatory fields in an application. where as stress test means,Finding the break point of an application is Stress testing. At a time load is Stress on the application.

Eg: client mentions no. Of users. Let us assume 25. In this context Load & Stress will be as follows.

Load: one by one hits the application up to 25 users

Stress: At a time 25 users hits on the application

Load Testing:
Applying the heavy loads
SressTesting:
Applying the heavy repetations

Load testing - testing an application under heavy loads, such as testing of a web site under a range of loads to determine at what point the system's response time degrades or fails.

Stress testing - term often used interchangeably with 'load' and 'performance' testing. Also used to describe such tests as system functional testing while under unusually heavy loads, heavy repetition of certain actions or inputs, input of large numerical values, large complex queries to a database system, etc.
