You don't, you read the tolerance markings. If you measure the resistor and it is outside the marked tolerance it is bad.
Resistor tolerance is how accurate the resistor value is. You may have a 10% tolerance, 820 ohm resistor, which means the actual value of resistance is 820 ohms +/- 82 ohms. If you design a circuit that has very stringent requirements for resistor values, you may need to purchase a resistor that has a smaller tolerance (like 5, 2, 1, .5%). The smaller the tolerance, the more expensive it will be (generally).
The minimum and maximum possible value is defined by the tolerance. To calculate the range of the resistor, simply add or remove the amount of the tolerance. For example, a 100Kohm resistor with 5% tolerance can range from 95Kohm through until 105Kohm. The lower the tolerance, the more accurate the resistor is.

A 1 ohm 20% tolerance resistor should not exceed 1.2 ohms actual resistance.
According to the EIA-96 system which applies to SMD resistors, it means 10K (10,000 ohm), 5% tolerance.
The colored bands on a resistor represent the resistor value and tolerance. The first two bands indicate the significant digits of the resistance value, the third band represents the multiplier, and the fourth band (if present) indicates the tolerance of the resistor. By decoding these colors, you can determine the resistance value of the resistor.
