• Optimize memory usage by closing unnecessary programs and services

• Increase virtual memory or add more RAM if necessary

• Check for memory leaks in applications and fix them

• Consider upgrading hardware if issue persists

Test case writing techniques include boundary value analysis, equivalence partitioning, decision table testing, and exploratory testing.

• Boundary value analysis involves testing the boundaries of input values.

• Equivalence partitioning involves dividing input values into groups that are expected to behave similarly.

• Decision table testing involves creating a table to map inputs to expected outputs.

• Exploratory testing ...read more
